      staging: vc04_services: clarify firmware dependency · 6fde3789
      Arnd Bergmann authored 
      The raspberrypi-firmware driver may be built as a loadable module,
which causes a link-time failure if the vc04_services driver is
built-in during compile-testing:

drivers/staging/vc04_services/vchiq.o: In function `vchiq_probe':
vchiq_connected.c:(.text.vchiq_probe+0x2c): undefined reference to `rpi_firmware_get'
drivers/staging/vc04_services/vchiq.o: In function `vchiq_platform_init':
vchiq_connected.c:(.text.vchiq_platform_init+0x1f0): undefined reference to `rpi_firmware_property'

This extends the dependency list to ensure the firmware is either
reachable, or completely disabled in case of compile-testing.

      staging: vc04_services: remove duplicate mutex_lock_interruptible · b826d73b
      Arnd Bergmann authored 
      The driver tries to redefine mutex_lock_interruptible as an open-coded
mutex_lock_killable, but that definition clashes with the normal
mutex_lock_interruptible definition when CONFIG_DEBUG_LOCK_ALLOC
is set:

staging/vc04_services/interface/vchiq_arm/vchiq_killable.h:67:0: error: "mutex_lock_interruptible" redefined [-Werror]
 #define mutex_lock_interruptible mutex_lock_interruptible_killable
include/linux/mutex.h:161:0: note: this is the location of the previous definition

This simply removes the private implementation and uses the
normal mutex_lock_killable directly.

We could do the same for the down_interruptible_killable here, but
it's better to just remove the semaphores entirely from the driver,
which also takes care of that.

      staging: wilc1000: simplify vif[i]->ndev accesses · 735bb39c
      Arnd Bergmann authored 
      With gcc-7, I got a new warning for this driver:

wilc1000/linux_wlan.c: In function 'wilc_netdev_cleanup':
wilc1000/linux_wlan.c:1224:15: error: 'vif[1]' may be used uninitialized in this function [-Werror=maybe-uninitialized]
wilc1000/linux_wlan.c:1224:15: error: 'vif[0]' may be used uninitialized in this function [-Werror=maybe-uninitialized]

A closer look at the function reveals that it's more complex than
it needs to be, given that based on how the device is created
we always get

	netdev_priv(vif->ndev) == vif

Based on this assumption, I found a few other places in the same file
that can be simplified. That code appears to be a relic from times
when the assumption above was not valid.

      Merge tag 'iio-for-4.10c' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

Third set of IIO new device support, features and cleanup for the 4.10 cycle.

Includes Peter Rosin's interesting drivers for a comparator. First complex
use we have had with an analog front end made from discrete components.

Brian Masney's work on moving the tsl2583 driver out of staging also
feature extensively!

New Drivers
* DAC based on a digital potentiometer
  - New driver for the use of a dpot as a DAC. Includes bindings and Axentia
  entry in vendor prefixes.
* Envelope detector baed on DAC and a comparator including device tree
  bindings.

Staging Graduation
* tsl2583.

Core new features
- Core provision for _available attributes.   This one had been stalled for
  a long time until Peter picked it up and ran with it!
- In kernel interface helpers to retrieve available info from channels.

Driver new features
* mcp4531
  - Add range of available raw values (used for the dpot dac driver).

Driver cleanups and fixes for issues introduced
* ad7766
  - Testing the wrong variable following devm_regulator_bulk_get introduced
  with the driver earlier in this cycle.
* ad9832
  - Fix a wrong ordering in the probe introduced in the previous set of
    patches.  A use before allocation bug.
* cros_ec_sensors
  - Testing for an error in a u8 will never work.
* mpu3050
  - Remove duplicate initializer for the module owner.
  - Add missing i2c dependency.
  - Inform the i2c mux core how it is used - step one in implifying device
  tree bindings.
* st-sensors
  - Get rid of large number of uninformative defines in favour of putting the
  constants where they are relevant. It is clear what they are from where
  they are used.
* tsl2583
  - Fix unused function warning when CONFIG_PM disabled and remove the
  ifdefs in favour of __maybe_unused.
  - Refactor taos_chip_on  to only read relevant registers.
  - Make sure calibscale and integration time are being set.
  - Verify chip is in ready to be used before calibration.
  - Remove some repeated checks for chip status (it's protected by a mutex
  so can't change until it's released)
  - Change current state storage from a tristate enum to a boolean seeing as
  only two values are actually used now.
  - Drop a redundant write to the control regiser in taos_probe (it's a noop)
  - Drop the FSF mailing address.
  - Clean up logging to not use hard coded function names (use __func__
  instead).
  - Cleanup up variable and function name prefixes.
  - Alignment of #define fixes.
  - Fix comparison between signed and unsigned integer warnings.
  - Add some newlines in favour of readability.
  - Combine the two sysfs ABI docs that somehow ended up in different places.
  - Fix multiline comment syntax.
  - Move a code block to inside an else statement as it makes more sense there.
  - Change tsl2583_als_calibrate to return 0 rather than a value nothing
  reads.
  - Drop some pointless brackets
  - Don't assume 32bit unsigned int.
  - Change to a per device instance lux table.
  - Add missing tsl2583 to the list of supported devices in the intro comments.
  - Improve commment on clearing of interrupts.
  - Drop some uninformative comments.
  - Drop a memset call that doesn't do anything useful any more.
  - Don't initialize some return variables that are always set.
  - Add Brian Masney as a module author after all these changes.

      staging: comedi: ni_mio_common: remove variable 'dl' in ni_ai_insn_read() · e3007002
      Ian Abbott authored 
      In `ni_ai_insn_read()`, local variable `dl` is declared as `unsigned
long`, but `unsigned int` will do.  Get rid of it and use local variable
`d` instead.  (That used to be `unsigned short`, but has been `unsigned
int` since kernel version 3.18.)

      staging: comedi: ni_mio_common: fix E series ni_ai_insn_read() data · 857a6610
      Ian Abbott authored 
      Commit 0557344e ("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 9c340ac9 ("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.
