On failure we were jumping to error_out0 where we were trying
sdio_release_host() but at this point of execution we still have not
done sdio_claim_host() and as a result host->claimed can still be 0.
And if host->claimed is 0 then WARN_ON(!host->claimed) will give
a warning.
Moreover, if it is still not claimed then mmc_host->claim_cnt will be 0
and mmc_release_host() will do "if (--host->claim_cnt)" and thus the
condition will become true.
Lets just return the value on allocation failure instead of trying to
release the host before claiming it.

Commit aa71987472a9 ("nvme: fabrics drivers don't need the nvme-pci
driver") removed the dependency on BLK_DEV_NVME, but the cdoe does
depend on the block layer (which used to be an implicit dependency
through BLK_DEV_NVME).
Otherwise you get various errors from the kbuild test robot random
config testing when that happens to hit a configuration with BLOCK
device support disabled.

Pull libnvdimm fixes from Dan Williams:
"nvdimm fixes for v4.8, two of them are tagged for -stable:
- Fix devm_memremap_pages() to use track_pfn_insert(). Otherwise,
DAX pmd mappings end up with an uncached pgprot, and unusable
performance for the device-dax interface. The device-dax interface
appeared in 4.7 so this is tagged for -stable.
- Fix a couple VM_BUG_ON() checks in the show_smaps() path to
understand DAX pmd entries. This fix is tagged for -stable.
- Fix a mis-merge of the nfit machine-check handler to flip the
polarity of an if() to match the final version of the patch that
Vishal sent for 4.8-rc1. Without this the nfit machine check
handler never detects / inserts new 'badblocks' entries which
applications use to identify lost portions of files.
- For test purposes, fix the nvdimm_clear_poison() path to operate on
legacy / simulated nvdimm memory ranges. Without this fix a test
can set badblocks, but never clear them on these ranges.
- Fix the range checking done by dax_dev_pmd_fault(). This is not
tagged for -stable since this problem is mitigated by specifying
aligned resources at device-dax setup time.
These patches have appeared in a next release over the past week. The
recent rebase you can see in the timestamps was to drop an invalid fix
as identified by the updated device-dax unit tests [1]. The -mm
touches have an ack from Andrew"

Bad blocks can be injected via /sys/block/pmemN/badblocks. In a situation
where legacy pmem is being used or a pmem region created by using memmap
kernel parameter, the injected bad blocks are not cleared due to
nvdimm_clear_poison() failing from lack of ndctl function pointer. In
this case we need to just return as handled and allow the bad blocks to
be cleared rather than fail.

virtio_console uses a small DMA buffer for control requests. Move
that buffer into heap memory.
Doing virtio DMA on the stack is normally okay on non-DMA-API virtio
systems (which is currently most of them), but it breaks completely
if the stack is virtually mapped.
Tested by typing both directions using picocom aimed at /dev/hvc0.

usb: fixes for v4.8-rc6
Unfortunately we have a bogus dwc3 patch leaked through the cracks and
got merged into Linus' HEAD. That patch ended up causing off-by-1 error
in our TRB accounting logic. Thankfully John Youn found out the problem
and we provided a revert to the bogus dwc3 patch in no time.
Apart from this off-by-1 error, we have two fixes to the Renesas drivers,
a small fix to our generic phy driver, a NULL pointer dereference fix for
f_eem and a build warning fix in dwc3.

Second set of IIO fixes for the 4.8 cycle.
We have a big rework of the kxsd9 driver queued up behind the fix below and
a fix for a recent fix that was marked for stable.
Hence this fix series is perhaps a little more urgent than average for IIO.
* core
- a fix for a fix in the last set. The recent fix for blocking ops when
! task running left a path (unlikely one) in which the function return
value was not set - so initialise it to 0.
- The IIO_TYPE_FRACTIONAL code previously didn't cope with negative
fractions. Turned out a fix for this was in Analog's tree but hadn't made
it upstream.
* bmc150
- reset chip at init time. At least one board out there ends up coming up
in an unstable state due to noise during power up. The reset does no
harm on other boards.
* kxsd9
- Fix a bug in the reported scaling due to failing to set the integer
part to 0.
* hid-sensors-pressure
- Output was in the wrong units to comply with the IIO ABI.
* tools
- iio_generic_buffer: Fix the trigger-less mode by ensuring we don't fault
out for having no trigger when we explicitly said we didn't want to have
one.

Problems with the signal integrity of the high speed USB data lines or
noise on reference ground lines can cause the i.MX6 USB controller to
violate USB specs and exhibit unexpected behavior.
It was observed that USBi_UI interrupts were triggered first and when
isr_setup_status_phase was called, ci->status was NULL, which lead to a
NULL pointer dereference kernel panic.
This patch fixes the kernel panic, emits a warning once and returns
-EPIPE to halt the device and let the host get stalled.
It also adds a comment to point people, who are experiencing this issue,
to their USB hardware design.

Depending on a number of factors including:
- Which exact Rockchip SoC we're working with
- How deep we suspend
- Which i2c port we're on
We might lose the state of the i2c registers at suspend time.
Specifically we've found that on rk3399 the i2c ports that are not in
the PMU power domain lose their state with the current suspend depth
configured by ARM Tursted Firmware.
Note that there are very few actual i2c registers that aren't configured
per transfer anyway so all we actually need to re-configure are the
clock config registers. We'll just add a call to rk3x_i2c_adapt_div()
at resume time and be done with it.
NOTE: On rk3399 on ports whose power was lost, I put printouts in at
resume time. I saw things like:
before: con=0x00010300, div=0x00060006
after: con=0x00010200, div=0x00180025

There are several ways to set the SDA hold time for i2c controller,
including: Device Tree, built-in device properties and ACPI. However,
if the SDA hold time is not specified by above method, we should
read the value, where it is preset by firmware, and save it to
sda_hold_time. This is needed because when i2c controller enters
runtime suspend, the DW_IC_SDA_HOLD value will be reset to chipset
default value. And during runtime resume, i2c_dw_init will be called
to reconfigure i2c controller. If sda_hold_time is zero, the chipset
default hold time will be used, that will be too short for some
platforms. Therefore, to have a better tolerance, the DW_IC_SDA_HOLD
value should be kept by sda_hold_time.
