[alsa-devel] [PATCH 00/17 v2] Update locking for snd_soc_dapm_xxxx_pin functions

[Charles Keepax]

This patchset updates the locking around the
snd_soc_dapm_xxxx_pin functions. First we add an unlocked
version of the functions and add locking to the standard
call, this also requires us to remove the few places where
these functions are externally locked. Then we patch usages
of the functions that look like they are expecting to do an
atomic update to do so, using external locking.

Thanks,
Charles

Updates since v1:
 - Added helper functions to lock/unlock the dapm mutex
 - Added an unlocked version of snd_soc_dapm_sync, so it can
   be called under the same mutex lock as the pin functions,
   this is not required just saves a mutex lock
