2021-05-03of: overlay: Remove redundant assignment to retJiapeng Chong
Variable ret is set to zero but this value is never read as it is overwritten with a new value later on, hence it is a redundant assignment and can be removed. Cleans up the following clang-analyzer warning: drivers/of/overlay.c:1197:2: warning: Value stored to 'ret' is never read [clang-analyzer-deadcode.DeadStores]. drivers/of/overlay.c:1026:2: warning: Value stored to 'ret' is never read [clang-analyzer-deadcode.DeadStores].

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "Here's a collection of largely clk driver updates. The usual suspects are here: i.MX, Qualcomm, Renesas, Allwinner, Samsung, and Rockchip, but it feels pretty light on commits. There's only one real commit to the framework core and that's to consolidate code. Otherwise the diffstat is dominated by many Qualcomm clk driver patches that modernize the driver for the proper way of speciying clk parents. That's shifting data around, which could subtly break things so I'll be on the lookout for fixes. New Drivers: - Proper clk driver for Mediatek MT7621 SoCs - Support for the clock controller on the new Rockchip rk3568 Updates: - Simplify Zynq Kconfig dependencies - Use clk_hw pointers in socfpga driver - Cleanup parent data in qcom clk drivers - Some cleanups for rk3399 modularization - Fix reparenting of i.MX UART clocks by initializing only the ones associated to stdout - Correct the PCIE clocks for i.MX8MP and i.MX8MQ - Make i.MX LPCG and SCU clocks return on registering failure - Kernel doc fixes - Add DAB hardware accelerator clocks on Renesas R-Car E3 and M3-N - Add timer (TMU) clocks on Renesas R-Car H3 ES1.0 - Add Timer (TMU & CMT) and thermal sensor (TSC) clocks on Renesas R-Car V3U - Sigma-delta modulation on Allwinner V3s audio PLL" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (82 commits) MAINTAINERS: add MT7621 CLOCK maintainer staging: mt7621-dts: use valid vendor 'mediatek' instead of invalid 'mtk' staging: mt7621-dts: make use of new 'mt7621-clk' clk: ralink: add clock driver for mt7621 SoC clk: uniphier: Fix potential infinite loop clk: qcom: rpmh: add support for SDX55 rpmh IPA clock clk: qcom: gcc-sdm845: get rid of the test clock clk: qcom: convert SDM845 Global Clock Controller to parent_data dt-bindings: clock: separate SDM845 GCC clock bindings clk: qcom: apss-ipq-pll: Add missing MODULE_DEVICE_TABLE clk: qcom: a53-pll: Add missing MODULE_DEVICE_TABLE clk: qcom: a7-pll: Add missing MODULE_DEVICE_TABLE dt: bindings: add mt7621-sysc device tree binding documentation dt-bindings: clock: add dt binding header for mt7621 clocks clk: samsung: Remove redundant dev_err calls clk: zynqmp: pll: add set_pll_mode to check condition in zynqmp_pll_enable clk: zynqmp: move zynqmp_pll_set_mode out of round_rate callback clk: zynqmp: Drop dependency on ARCH_ZYNQMP clk: zynqmp: Enable the driver if ZYNQMP_FIRMWARE is selected clk: qcom: gcc-sm8350: use ARRAY_SIZE instead of specifying num_parents ...

Currently the for-loop in ksz8_port_init_cnt is causing a static analysis infinite loop warning with the comparison of mib->cnt_ptr < dev->reg_mib_cnt. This occurs because mib->cnt_ptr is a u8 and dev->reg_mib_cnt is an int and the analyzer determines that mib->cnt_ptr potentially can wrap around to zero if the value in dev->reg_mib_cnt is > 255. However, this value is never this large, it is always less than 256 so make reg_mib_cnt a u8.

Even though I'm sure the current code is ok, I totally dislike that s390 is the only architecture being special here; especially considering that there was a lengthly discussion about this topic and the outcome was not to use the builtins. Therefore open-code atomic ops again with inline assembly and switch to gcc builtins as soon as other architectures are doing. - couple of other changes to atomic and cmpxchg, and use atomic-instrumented.h for KASAN. - separate zbus creation, registration, and scanning in our PCI code which allows for cleaner and easier handling. - a rather large change to the vfio-ap code to fix circular locking dependencies when updating crypto masks. - move QAOB handling from qdio layer down to drivers. - add CRW inject facility to common I/O layer. This adds debugs files which allow to generate artificial events from user space for testing purposes. - increase SCLP console line length from 80 to 320 characters to avoid odd wrapped lines. - add protected virtualization guest and host indication files, which indicate either that a guest is running in pv mode or if the hypervisor is capable of starting pv guests. - various other small fixes and improvements all over the place. * tag 's390-5.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (53 commits) s390/disassembler: increase ebpf disasm buffer size s390/archrandom: add parameter check for s390_arch_random_generate s390/zcrypt: fix zcard and zqueue hot-unplug memleak s390/pci: expose a PCI device's UID as its index s390/atomic,cmpxchg: always inline __xchg/__cmpxchg s390/smp: fix do_restart() prototype s390: get rid of oprofile leftovers s390/atomic,cmpxchg: make constraints work with old compilers s390/test_unwind: print test suite start/end info s390/cmpxchg: use unsigned long values instead of void pointers s390/test_unwind: add WARN if tests failed s390/test_unwind: unify error handling paths s390: update defconfigs s390/spinlock: use R constraint in inline assembly s390/atomic,cmpxchg: switch to use atomic-instrumented.h s390/cmpxchg: get rid of gcc atomic builtins s390/atomic: get rid of gcc atomic builtins s390/atomic: use proper constraints s390/atomic: move remaining inline assemblies to atomic_ops.h s390/bitops: make bitops only work on longs ...
2021-04-27Fix misc new gcc warningsLinus Torvalds
It seems like Fedora 34 ends up enabling a few new gcc warnings, notably "-Wstringop-overread" and "-Warray-parameter". Both of them cause what seem to be valid warnings in the kernel, where we have array size mismatches in function arguments (that are no longer just silently converted to a pointer to element, but actually checked). This fixes most of the trivial ones, by making the function declaration match the function definition, and in the case of intel_pm.c, removing the over-specified array size from the argument declaration. At least one 'stringop-overread' warning remains in the i915 driver, but that one doesn't have the same obvious trivial fix, and may or may not actually be indicative of a bug.

2021-04-27sfc: adjust efx->xdp_tx_queue_count with the real number of initialized queuesIgnat Korchagin

2021-04-27net: phy: Add support for microchip SMI0 MDIO busAndrew Lunn
SMI0 is a mangled version of MDIO. The main low level difference is the MDIO C22 OP code is always 0, not 0x2 or 0x1 for Read/Write. The read/write information is instead encoded in the PHY address. Extend the bit-bang code to allow the op code to be overridden, but default to normal C22 values. Add an extra compatible to the mdio-gpio driver, and when this compatible is present, set the op codes to 0. A higher level driver, sitting on top of the basic MDIO bus driver can then implement the rest of the microchip SMI0 odderties.

Although HWTSTAMP_TX_ONESTEP_SYNC existed in ioctl for hardware timestamp configuration, the PTP Sync one-step timestamping had never been supported. This patch is to truely support it. - ocelot_port_txtstamp_request() This function handles tx timestamp request by storing ptp_cmd(tx timestamp type) in OCELOT_SKB_CB(skb)->ptp_cmd, and additionally for two-step timestamp storing ts_id in OCELOT_SKB_CB(clone)->ptp_cmd. - ocelot_ptp_rew_op() During xmit, this function is called to get rew_op (rewriter option) by checking skb->cb for tx timestamp request, and configure to transmitting. Non-onestep-Sync packet with one-step timestamp request falls back to use two-step timestamp.

Free skb->cb usage in core driver and let device drivers decide to use or not. The reason having a DSA_SKB_CB(skb)->clone was because dsa_skb_tx_timestamp() which may set the clone pointer was called before p->xmit() which would use the clone if any, and the device driver has no way to initialize the clone pointer. This patch just put memset(skb->cb, 0, sizeof(skb->cb)) at beginning of dsa_slave_xmit(). Some new features in the future, like one-step timestamp may need more bytes of skb->cb to use in dsa_skb_tx_timestamp(), and p->xmit().

It was a waste to clone skb directly in dsa_skb_tx_timestamp(). For one-step timestamping, a clone was not needed.

The .serdes_get_lane op used the magic value 0xff to indicate a valid SERDES lane and 0 signaled that a non-SERDES mode was set on the port. Unfortunately, "0" is also a valid lane ID, so even when these ports where configured to e.g. RGMII the driver would set them up as SERDES ports. - Replace 0xff with 0 to indicate a valid lane ID. The number is on the one hand just as arbitrary, but it is at least the first valid one and therefore less of a surprise. - Follow the other .serdes_get_lane implementations and return -ENODEV in the case where no SERDES is assigned to the port.
