      staging:iio:ad5933: Drop "raw" from channel names · 6822ee34
      Lars-Peter Clausen authored 
      "raw" is the name of a channel property, but should not be part of the
channel name itself.

      staging:iio:ad5933: Fix NULL pointer deref when enabling buffer · 824269c5
      Lars-Peter Clausen authored 
      In older versions of the IIO framework it was possible to pass a
completely different set of channels to iio_buffer_register() as the one
that is assigned to the IIO device. Commit 959d2952 ("staging:iio: make
iio_sw_buffer_preenable much more general.") introduced a restriction that
requires that the set of channels that is passed to iio_buffer_register() is
a subset of the channels assigned to the IIO device as the IIO core will use
the list of channels that is assigned to the device to lookup a channel by
scan index in iio_compute_scan_bytes(). If it can not find the channel the
function will crash. This patch fixes the issue by making sure that the same
set of channels is assigned to the IIO device and passed to
iio_buffer_register().

Fixes the follow NULL pointer derefernce kernel crash:

      Pull ARM fixes from Russell King:
 "Fixes for ARM, the most notable being the fix from Nathan Lynch to fix
  the state of various registers during execve, to ensure that data
  can't be leaked between two executables.

  Fixes from Victor Kamensky for get_user() on big endian platforms,
  since the addition of 8-byte get_user() support broke these fairly
  badly.

  A fix from Sudeep Holla for affinity setting when hotplugging CPU 0.

  A fix from Stephen Boyd for a perf-induced sleep attempt while atomic.

  Lastly, a correctness fix for emulation of the SWP instruction on
  ARMv7+, and a fix for wrong carry handling when updating the
  translation table base address on LPAE platforms"

  ARM: 8148/1: flush TLS and thumbee register state during exec
  ARM: 8151/1: add missing exports for asm functions required by get_user macro
  ARM: 8137/1: fix get_user BE behavior for target variable with size of 8 bytes
  ARM: 8135/1: Fix in-correct barrier usage in SWP{B} emulation
