Gustavo A. R. Silva b24d10976e staging: iio: adc: fix error return code in ad7606_par_probe()
platform_get_irq() returns an error code, but the ad7606_par driver
ignores it and always returns -ENODEV. This is not correct and,
prevents -EPROBE_DEFER from being propagated properly.

Print and propagate the return value of platform_get_irq on failure.

This issue was detected with the help of Coccinelle.

Andy Shevchenko fb4b6f92d1 iio: adc: ti-ads7950: Add OF device ID table
The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
SPI device registered via OF will always match a legacy SPI device ID and
that the MODALIAS reported will always be of the form spi:<device>.

There is an ACPI method to enumerate such devices via specific ACPI ID
and use of compatible strings. It will not work for the drivers which
have no OF match ID table present.

Besides this could change in the future so the correct approach is to
have an OF device ID table if the devices are registered via OF.

Fabrice Gasnier ee2ac1cdd3 iio: adc: stm32: add optional st,min-sample-time-nsecs
STM32 ADC allows each channel to be sampled with a different sampling time,
by setting SMPR registers. Basically, value depends on local electrical
properties. Selecting correct value for sampling time highly depends on
analog source impedance. There is a manual that may help in this process:
'How to get the best ADC accuracy in STM32...'

This patch allows to configure minimum sampling time via device tree,
either for:
- all channels at once:
  st,min-sample-time-nsecs = <10000>;

- independently for each channel (must match "st,adc-channels" list):
  st,adc-channels = <0 1>;
  st,min-sample-time-nsecs = <5000 10000>;

Jacob von Chorus a46393aba7 staging: gs_fpgaboot: add buffer overflow checks
Four fields in struct fpgaimage are char arrays of length MAX_STR (256).
The amount of data read into these buffers is controlled by a length
field in the bitstream file read from userspace. If a corrupt or
malicious firmware file was supplied, kernel data beyond these buffers
can be overwritten arbitrarily.

This patch adds a check of the bitstream's length value to ensure it
fits within the bounds of the allocated buffers. An error condition is
returned from gs_read_bitstream if any of the reads fail.

Greg Kroah-Hartman 98c2f10d23 First round of IIO new device support, features and cleanups for the 4.14 cycle.
4 completely new drivers in this set and plenty of other stuff.
 
 One ABI change due to a silly mistake a long time back. Hopefully no
 one will notice.  It effects the numerical order of consumer device
 channels which was the reverse of the obvious.  It's going the slow
 way to allow us some margin to spot if we have broken userspace or
 not (seems unlikely)
 
 New Device Support
 * ccs811
   - new driver for the Volatile Organic Compounds (VOC) sensor.
 * dln2 adc
   - new driver for the ADC on this flexible usb board.
 * EP93xx
   - new driver for this Cirrus logic SoC ADC.
 * ltc2471
   - new ADC driver support the ltc2471 and ltc2473
 * st_accel
   - add trivial table entries to support H3LIS331DL, LIS331DL, LIS3LV02DL.
 * st_gyro
   - add L3GD20H support (again) having fixed the various things that were
     broken in the first try.  Includes devicetree binding.
 * stm32 dac
   - add support for the DACs in the STM32F4 series
 
 Features
 * Documentation
   - add missing power attribute documentation to the ABI docs.
 * at91-sama5d2
   - add hardware trigger and buffered capture support with bindings.

Merge tag 'iio-for-4.14a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

First round of IIO new device support, features and cleanups for the 4.14 cycle.

4 completely new drivers in this set and plenty of other stuff.

One ABI change due to a silly mistake a long time back. Hopefully no
one will notice.  It effects the numerical order of consumer device
channels which was the reverse of the obvious.  It's going the slow
way to allow us some margin to spot if we have broken userspace or
not (seems unlikely)

New Device Support
* ccs811
  - new driver for the Volatile Organic Compounds (VOC) sensor.
* dln2 adc
  - new driver for the ADC on this flexible usb board.
* EP93xx
  - new driver for this Cirrus logic SoC ADC.
* ltc2471
  - new ADC driver support the ltc2471 and ltc2473
* st_accel
  - add trivial table entries to support H3LIS331DL, LIS331DL, LIS3LV02DL.
* st_gyro
  - add L3GD20H support (again) having fixed the various things that were
    broken in the first try.  Includes devicetree binding.
* stm32 dac
  - add support for the DACs in the STM32F4 series

Features
* Documentation
  - add missing power attribute documentation to the ABI docs.
* at91-sama5d2
  - add hardware trigger and buffered capture support with bindings.
  - suspend and resume functionality.
* bmc150
  - support for the BOSC0200 ACPI device id seen on some tablets.
* hdc100x
  - devicetree bindings
  - document supported devices
  - match table and device ids.
