gcc notices that we would overflow the buffer for the
inquiry of the product name if we have too many adapters:
drivers/scsi/gdth.c: In function 'gdth_next':
drivers/scsi/gdth.c:2357:29: warning: 'sprintf' may write a terminating nul past the end of the destination [-Wformat-overflow=]
sprintf(inq.product,"Host Drive #%02d",t);
^~~~~~~~~~~~~~~~~~~
drivers/scsi/gdth.c:2357:9: note: 'sprintf' output between 16 and 17 bytes into a destination of size 16
sprintf(inq.product,"Host Drive #%02d",t);
This won't happen in practice, so just use snprintf to
truncate the string.

We print the driver name into one string and then add and ID
and copy it into a second string of the same length, at which
point gcc complains about a possible overflow:
drivers/scsi/mpt3sas/mpt3sas_scsih.c: In function '_scsih_probe':
drivers/scsi/mpt3sas/mpt3sas_scsih.c:8884:21: error: '_cm' directive writing 3 bytes into a region of size between 1 and 32 [-Werror=format-overflow=]
printf(ioc->name, "%s_cm%d", ioc->driver_name, ioc->id);
^~~~~~~~~
drivers/scsi/mpt3sas/mpt3sas_scsih.c:8884:21: note: directive argument in the range [0, 255]
drivers/scsi/mpt3sas/mpt3sas_scsih.c:8884:2: note: 'sprintf' output between 5 and 38 bytes into a destination of size 32
sprintf(ioc->name, "%s_cm%d", ioc->driver_name, ioc->id);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Making the first string shorter is sufficient to avoid the
warning here, as we know it can only contain either "mpt2sas"
or "mpt3sas".

gcc-7 complains that the firmware version strings might overflow
for some values:

drivers/scsi/megaraid.c:320:3: note: 'sprintf' output between 7 and 9 bytes into a destination of size 7
This makes the code use a truncating snprintf() instead, which shuts
up that warning.

Limit PDMA send to 512 B to avoid data corruption on DTC3181E. The
corruption is always the same: one byte missing at the beginning of a
128 B block. It happens only with slow Quantum LPS 240 drive, not with
faster IBM DORS-32160. It's not clear what causes this. Documentation
for the DTC436 chip has not been made available.

The polling loops in pread() and pwrite() can easily become infinite
loops and hang the machine.
Merge the IRQ check into host buffer wait loop and add polling limit.
Also place a limit on polling for 53C80 registers accessibility.
[Use NCR5380_poll_politely2() for register polling. Rely on polling for
gated IRQ rather than polling for phase error, like the algorithm in the
53c400 datasheet. Move DTC436 workarounds into a separate patch.
Factor-out common code as wait_for_53c80_access(). Rework the residual
calculations. -- F.T.]

When an IRQ arrives during PDMA transfer, pread() and pwrite() return
without waiting for the 53C80 registers to be ready and this ends up
messing up the chip state. This was observed with SONY CDU-55S which is
slow enough to disconnect during 4096-byte reads.
IRQ during PDMA is not an error so don't return -1. Instead, store the
remaining byte count for use by NCR5380_dma_residual().
[Poll for the BASR_END_DMA_TRANSFER condition rather than remove the
error message -- F.T.]

"Fix loop preventing some platforms from waking up via the power button

* tag 'platform-drivers-x86-v4.13-4' of git://git.infradead.org/linux-platform-drivers-x86:
platform/x86: intel-vbtn: match power button on press rather than release
|
|
This fixes a problem where the system gets stuck in a loop
unable to wakeup via power button in s2idle.
The problem happens because:
- press power button:
- system emits 0xc0 (power press), event ignored
- system emits 0xc1 (power release), event processed,
emited as KEY_POWER
- set wakeup_mode to true
- system goes to s2idle
- press power button
- system emits 0xc0 (power press), wakeup_mode is true,
system wakes
- system emits 0xc1 (power release), event processed,
emited as KEY_POWER
- system goes to s2idle again
To avoid this situation, process the presses (which matches what
intel-hid does too).

- cleanup media SVG files, in order to fix PDF build on some distros
- fix random Kconfig build of venus driver

"A handful of critical fixes for changes introduce this merge window.
- The TI sci_clk_get() API was pretty broken and nobody noticed.
- There were some CPUfreq crashes on C.H.I.P devices because we

- Also, the Intel Atom PMC clk driver needs to mark a clk critical if
the firmware has it enabled already so that audio doesn't get
killed on Baytrail.
- Gemini devices have a dead serial console because the reset control
usage in the serial driver assume one method of reset that gemini
doesn't support (this will be fixed in the next version in the
reset framework so this is the small fix for -rc series).
- Finally we have two rate calculation fixes, one for Exynos and one

Pull power management fixes from Rafael Wysocki:
"These fix two cpufreq issues, one introduced recently and one related
to recent changes, fix cpufreq documentation, fix up recently added
code in the Thunderbolt driver and update runtime PM framework
documentation.
Specifics:
- Fix the handling of the scaling_cur_freq cpufreq policy attribute
on x86 systems with the MPERF/APERF registers present to make it
behave more as expected after recent changes (Rafael Wysocki).
- Drop a leftover callback from the intel_pstate driver which also
prevents the cpuinfo_cur_freq cpufreq policy attribute from being
incorrectly exposed when intel_pstate works in the active mode
(Rafael Wysocki).
- Add a missing piece describing the cpuinfo_cur_freq policy
attribute to cpufreq documentation (Rafael Wysocki).
- Fix up a recently added part of the Thunderbolt driver to avoid
aborting system suspends if its mailbox commands time out (Rafael
Wysocki).
- Update device runtime PM framework documentation to reflect the
current behavior of the code (Johan Hovold)"

The commit 304419d8a7e9 ("mmc: core: Allocate per-request data using the
block layer core") refactored mechanism of queue handling caused
mmc_init_request() can be called just after mmc_cleanup_queue() caused null
pointer dereference.
Another commit bbdc74dc19e0 ("mmc: block: Prevent new req entering queue
after its cleanup") tried to fix the problem. However it actually miss one
corner case.
We could still reproduce the issue mentioned with these steps:
(1) insert a SD card and mount it
(2) hotplug it, so it will leave md->usage still be counted
(3) reboot the system which will sync data and umount the card

So mmc_blk_put wouldn't calling blk_cleanup_queue which actually the
QUEUE_FLAG_DYING and QUEUE_FLAG_BYPASS should stay. Block core expect
blk_queue_bypass_{start, end} internally to bypass/drain the queue before
actually dying the queue, so it didn't expose API to set the queue bypass.
I think we should set QUEUE_FLAG_BYPASS whenever queue is removed, although
the md->usage is still counted, as no dispatch queue could be found then.

When the device is non removable, the card detect signal is often used
for another purpose i.e. muxed to another SoC peripheral or used as a
GPIO. It could lead to wrong behaviors depending the default value of
this signal if not muxed to the SDHCI controller.

Currently a bug in the sci_clk_get implementation causes it to always
return a clock belonging to the last device in the static list of clock
data. This is due to a bug in the init code that causes the array
used by sci_clk_get to only be populated with the clocks for the last
device, as each device overwrites the entire array with its own clocks.
Fix this by calculating the actual number of clocks for the SoC, and
allocating the whole array in one go. Also, we don't need the handle
to the init data array anymore after doing this, instead we can
just compare the dev_id / clk_id against the registered clocks and
use binary search for speed.

As I was staring at the si_init_golden_registers code, I noticed that
the Pitcairn initialization silently falls through the Cape Verde
initialization, and the Oland initialization falls through the Hainan
initialization. However there is no comment stating that this is
intentional, and the radeon driver doesn't have any such fallthrough,
so I suspect this is not supposed to happen.
