commit 9d29f14db1095f52ca00b8162b242d6fce07d19f upstream.

wait_for_completion_interruptible_timeout return 0 on timeout and
-ERESTARTSYS if interrupted. The check for
!wait_for_completion_interruptible_timeout() would report an interrupt
as timeout. Further, while HZ/50 will work most of the time it could
fail for HZ < 50, so this is switched to msecs_to_jiffies(20).

commit 1335a9516d3d52f157ad87456efdd8dc9ae1747b upstream.

Commit fadbe0cd5292851608e2e01b91d9295fa287b9fe ("staging: rtl8188eu:
Remove rtw_zmalloc(), wrapper for kzalloc()") changed all allocation
calls to be GFP_KERNEL even though the original wrapper was testing
to determine if the caller was in atomic mode. Most of the mistakes
were corrected with commit 33dc85c3c667209c930b2dac5ccbc2a365e06b7a
("staging: r8188eu: Fix scheduling while atomic error introduced in
commit fadbe0cd"); however, two kzalloc calls were missed as the
call only happens when the driver is shutting down.

Don't return the confusing -EIO error code when the device is not registered,
instead return -ENODEV which is the proper thing to do in this situation.

If the adapter is configured as 'Unregistered', then cec_receive_notify
incorrectly thinks that broadcast messages are directed messages. The
destination for broadcast messages is 0xf, and the logical address
assigned to Unregistered devices is also 0xf and the logic didn't handle
that correctly.

First round of IIO fixes for the 4.8 cycle.

This is somewhat of a bumper set due to my unavailabilty earlier in the
month.  The only slightly unusual ones are the dts updates for the
rockchip adc reset.  The fix in the driver only makes sense with these
and the rockchip maintainer is happy with them going through IIO to
reach mainline.

Core stuff

* Fix an issue with a blocking op when !TASK_RUNNING. This been there
  a while and snuck in with seemingly minor additions to some core
  code paths.
* Tools
  - generic_buffer failed to initialize the channel array pointer thus
    in the case of no channels blows up trying to free a random memory
    address.
* sw-trigger:
  - Fix config group initialization when configfs is built as a module.

Drivers

* ad5933
  - Fix an incorrect overwrite of an error value.
* ad799x
  - A missed assignment of the update_scan_mode callback means buffered mode
    doesn't work on the ad7991, ad7995 or ad7999.
* ads1015
  - wrong pointer returned from i2c_get_clientdata (missmatch of assumptions)
* am2315
  - Timestamps are reported, but never actually acquired from anywhere
    (so always 0)
  - missing buffer selects in Kconfig
* am335x adc
  - Protect fifo1 from concurrent access.
  - Increase timeout waiting for ADC to be long enough in all cases.
* as3935
  - Timestamps are reported, but never actually acquired from anywhere
    (so always 0)
* at91
  - Fix reading of channel 3.
* atlas-ph-sensor
  - Typo means that the scale of electrical conductivity readings is way off.
* bma220
  - Timestamps are reported, but never actually acquired from anywhere
    (so always 0)
  - Missing buffer selects in Kconfig
* bmp280
  - pass the write pointer to PTR_ERR (i.e. the one that was just checked
    with IS_ERR).
  - suspend /resume crash due to wrong assumption about what dev_get_drvdata
    would return.
* hdc100x
  - It superficially appeared that smbus_read_byte commands would allow
  reading of the outputs in two goes.  In reality it doesn't work, but
  instead returns the same for the upper and lower bytes (nice catch from
  Alison!)
* kxsd9
  - Fix raw read return value to ensure it actually reports the value rather
  than a blank string.
* max44000
  - Missing buffer selects in Kconfig
* rockchip_saradc
  - Add use of reset controller to enforce a clean state of the ADC.
    Some bootloaders can leave it in an 'intersting' state and effectively
    frozen without this. A couple of associated dts updates.
* stk8ba50
  - Missing buffer selects in Kconfig
* stx104
  - Fix a possible race due to use of devm_iio_device_register when there
    was other stuff in the remove function.
