      ext2: Fix link count corruption under heavy link+rename load · e8a80c6f
      由 Josh Hunt 提交于 
      vfs_rename_other() does not lock renamed inode with i_mutex. Thus changing
i_nlink in a non-atomic manner (which happens in ext2_rename()) can corrupt
it as reported and analyzed by Josh.

In fact, there is no good reason to mess with i_nlink of the moved file.
We did it presumably to simulate linking into the new directory and unlinking
from an old one. But the practical effect of this is disputable because fsck
can possibly treat file as being properly linked into both directories without
writing any error which is confusing. So we just stop increment-decrement
games with i_nlink which also fixes the corruption.

      由 vwadekar@nvidia.com 提交于 
      tps6586 does not support burst writes. i2c writes have to be
1 byte at a time.

      mfd: Don't suspend WM8994 if the CODEC is not suspended · 77bd70e9
      由 Mark Brown 提交于 
      ASoC supports keeping the audio subsysetm active over suspend in order
to support use cases such as audio passthrough from a cellular modem
with the main CPU suspended. Ensure that we don't power down the CODEC
when this is happening by checking to see if VMID is up and skipping
suspend and resume when it is. If the CODEC has suspended then it'll
turn VMID off before the core suspend() gets called.

      mfd: Fix NULL pointer due to non-initialized ucb1x00-ts absinfo · 9063f1f1
      由 Jochen Friedrich 提交于 
      Call input_set_abs_params instead of manually setting absbit only.
This fixes this oops:
