commit eadf081146ec327d6fbbb6aff28e3d9aac329dc6 upstream.
A bugfix removed the two callers of s5p_cec_runtime_suspend
and s5p_cec_runtime_resume, leading to the return of a harmless
warning that I had previously fixed in commit aee8937089b1
("[media] s5p_cec: mark suspend/resume as __maybe_unused"):
staging/media/s5p-cec/s5p_cec.c:234:12: error: ‘s5p_cec_runtime_suspend’ defined but not used [-Werror=unused-function]
staging/media/s5p-cec/s5p_cec.c:242:12: error: ‘s5p_cec_runtime_resume’ defined but not used [-Werror=unused-function]
This adds the __maybe_unused annotations to the function that
were not removed and that are now unused when CONFIG_PM
is disabled.

commit b321a38d2407c7e425c54bc09be909a34e49f740 upstream.
The oversampling ratio is controlled using the oversampling pins,
OS [2:0] with OS2 being the MSB control bit, and OS0 the LSB control
bit.
The gpio connected to the OS2 pin is not being set correctly, only OS0
and OS1 pins are being set. Fix the typo to allow proper control of the
oversampling pins.

commit 857a661020a2de3a0304edf33ad656abee100891 upstream.
Commit 0557344e2149 ("staging: comedi: ni_mio_common: fix local var for
32-bit read") changed the type of local variable `d` from `unsigned
short` to `unsigned int` to fix a bug introduced in
commit 9c340ac934db ("staging: comedi: ni_stc.h: add read/write
callbacks to struct ni_private") when reading AI data for NI PCI-6110
and PCI-6111 cards. Unfortunately, other parts of the function rely on
the variable being `unsigned short` when an offset value in local
variable `signbits` is added to `d` before writing the value to the
`data` array:
d += signbits;
data[n] = d;
The `signbits` variable will be non-zero in bipolar mode, and is used to
convert the hardware's 2's complement, 16-bit numbers to Comedi's
straight binary sample format (with 0 representing the most negative
voltage). This breaks because `d` is now 32 bits wide instead of 16
bits wide, so after the addition of `signbits`, `data[n]` ends up being
set to values above 65536 for negative voltages. This affects all
supported "E series" cards except PCI-6143 (and PXI-6143). Fix it by
ANDing the value written to the `data[n]` with the mask 0xffff.

commit 655c4d442d1213b617926cc6d54e2a9a793fb46b upstream.
For NI M Series cards, the Comedi `insn_read` handler for the AI
subdevice is broken due to ANDing the value read from the AI FIFO data
register with an incorrect mask. The incorrect mask clears all but the
most significant bit of the sample data. It should preserve all the
sample data bits. Correct it.

commit b8cb86fd95bb461c3496e1f4b4083b198c963a9c upstream.
James Simmons reports:
> The ldlm_pool field pl_recalc_time is set to the current
> monotonic clock value but the interval period is calculated
> with the wall clock. This means the interval period will
> always be far larger than the pl_recalc_period, which is
> just a small interval time period. The correct thing to
> do is to use monotomic clock current value instead of the
> wall clocks value when calculating recalc_interval_sec.
This broke when I converted the 32-bit get_seconds() into
ktime_get_{real_,}seconds() inconsistently. Either
one of those two would have worked, but mixing them
does not.
Staying with the original intention of the patch, this
changes the ktime_get_seconds() calls into ktime_get_real_seconds(),
using real time instead of mononic time.

commit cd15dd6ef4ea11df87f717b8b1b83aaa738ec8af upstream.
I have been having a lot of unexplainable crashes in osc_lru_shrink
lately that I could not see a good explanation for and then I found
this patch that slip under the radar somehow that incorrectly
converted while loop for lru list iteration into
list_for_each_entry_safe totally ignoring that in the body of
the loop we drop spinlocks guarding this list and move list entries
around.
Not sure why it was not showing up right away, perhaps some of the
more recent LRU changes committed caused some extra pressure on this
code that finally highlighted the breakage.

This reverts commit 36b30d6138f4677514aca35ab76c20c1604baaad.
This is necessary to detect paz00 (ac100) touchpad properly as one
speaking ETPS/2 protocol. Without it X.org's synaptics driver doesn't
work as the touchpad is detected as an ImPS/2 mouse instead.
Commit ec6184b1c717b8768122e25fe6d312f609cc1bb4 changed the way
auto-detection is performed on ports marked as pass through and made the
issue apparent.
A pass through port is an additional PS/2 port used to connect a slave
device to a master device that is using PS/2 to communicate with the
host (so slave's PS/2 communication is tunneled over master's PS/2
link). "Synaptics PS/2 TouchPad Interfacing Guide" describes such a
setup (PS/2 PASS-THROUGH OPTION section).
Since paz00's embedded controller is not connected to a PS/2 port
itself, the PS/2 interface it exposes is not a pass-through one.

`ni_tio_clock_period_ps()` used to return the clock period in
picoseconds, and had a `BUG()` call for invalid cases. It was changed
to pass the clock period back via a pointer parameter and return an
error for the invalid cases. Unfortunately the code to handle
user-specified clock sources with user-specified clock period is still
returning the clock period the old way, which can lead to the caller not
getting the clock period, or seeing an unexpected error. Fix it by
passing the clock period via the pointer parameter and returning `0`.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus
Second set of IIO fixes for the 4.9 cycle.
Interestingly scale related fixes for accelerometers at both ends of
the range. Obviously more varied devices turning up than we've seen before!
* ad5933
- fix an uninitialized value in a return case that is winding up GCC.
* hid sensors
- missing pm function prevents hid rotations sensors from working on newer
ISH hubs (works by luck on older ones)
- increase of scale precision needed to fix a case where on a yoga 260
the reported scale is 0 (presumably a high precision but very low g sensor).
* st_sensors
- fix an issue seen with the hs3lis331dl where the range is much greater
than previous devices (100's of g) and hence the per bit scale is greater
than 1.

The ad5933_i2c_read function returns an error code to indicate
whether it could read data or not. However ad5933_work() ignores
this return code and just accesses the data unconditionally,
which gets detected by gcc as a possible bug:

drivers/staging/iio/impedance-analyzer/ad5933.c:649:16: warning: 'status' may be used uninitialized in this function [-Wmaybe-uninitialized]
This adds minimal error handling so we only evaluate the

This fix removes the unnecessary call to destroy_workqueue() while opening
the device to avoid the above kernel panic. The deinit routine already
does a good job of terminating the workqueue when no longer needed.

The mapping_set_error() helper sets the correct AS_ flag for the mapping
so there is no reason to open code it. Use the helper directly.

Current supplementary groups code can massively overallocate memory and
is implemented in a way so that access to individual gid is done via 2D
array.
If number of gids is <= 32, memory allocation is more or less tolerable
(140/148 bytes). But if it is not, code allocates full page (!)
regardless and, what's even more fun, doesn't reuse small 32-entry
array.
2D array means dependent shifts, loads and LEAs without possibility to
optimize them (gid is never known at compile time).
All of the above is unnecessary. Switch to the usual
trailing-zero-len-array scheme. Memory is allocated with
kmalloc/vmalloc() and only as much as needed. Accesses become simpler
(LEA 8(gi,idx,4) or even without displacement).
Maximum number of gids is 65536 which translates to 256KB+8 bytes. I
think kernel can handle such allocation.
On my usual desktop system with whole 9 (nine) aux groups, struct
group_info shrinks from 148 bytes to 44 bytes, yay!
Nice side effects:
- "gi->gid[i]" is shorter than "GROUP_AT(gi, i)", less typing,
- fix little mess in net/ipv4/ping.c
should have been using GROUP_AT macro but this point becomes moot,
- aux group allocation is persistent and should be accounted as such.

Pull staging and IIO updates from Greg KH:
"Here is the big staging and IIO driver pull request for 4.9-rc1.
There are a lot of patches in here, the majority due to the
drivers/staging/greybus/ subsystem being merged in with full
development history that went back a few years, in order to preserve
the work that those developers did over time.
Lots and lots of tiny cleanups happened in the tree as well, due to
the Outreachy application process and lots of other developers showing
up for the first time to clean code up. Along with those changes, we
deleted a wireless driver, and added a raspberrypi driver (currently
marked broken), and lots of new iio drivers.
Overall the tree still shrunk with more lines removed than added,
about 10 thousand lines removed in total. Full details are in the very
long shortlog below.
All of this has been in the linux-next tree with no issues. There will
be some merge problems with other subsystem trees, but those are all
minor problems and shouldn't be hard to work out when they happen
(MAINTAINERS and some lustre build problems with the IB tree)"
And furter from me asking for clarification about greybus:
"Right now there is a phone from Motorola shipping with this code (a
slightly older version, but the same tree), so even though Ara is not
alive in the same form, the functionality is happening. We are working
with the developers of that phone to merge the newer stuff in with
their fork so they can use the upstream version in future versions of
their phone product line.
Toshiba has at least one chip shipping in their catalog that
needs/uses this protocol over a Unipro link, and rumor has it that
there might be more in the future.
There are also other users of the greybus protocols, there is a talk
next week at ELC that shows how it is being used across a network
connection to control a device, and previous ELC talks have showed the
protocol stack being used over USB to drive embedded Linux boards.
I've also talked to some people who are starting to work to add a host
controller driver to control arduinos as the greybus PHY protocols are
very useful to control a serial/i2c/spio/whatever device across a
random physical link, as it is a way to have a self-describing device
be attached to a host without needing manual configuration.
So yes, people are using it, and there is still the chance that it
will show up in a phone/laptop/tablet/whatever from Google in the
future as well, the tech isn't dead, even if the original large phone
project happens to be"
