[PATCH v4 0/3] kselftest: alsa: Add basic mixer selftest

[Mark Brown]

This series adds a basic selftest for the mixer interface, as discussed
in the cover letter for the main patch there's plenty of additional
coverage that could be added but this is a good starting point.

v4:
 - More stylistic updates suggested by Shuah.
 - Fix build with older alsa-lib.
v3:
 - Pull in incremental updates adding a fixed library configuration from
   Jaroslav and support for volatile controls from Takashi Sakamoto.
 - Stylistic updates suggested by Shuah.
v2:
 - Use pkg-config to get CFLAGS and LDLIBS for alsa-lib.

Mark Brown (1):
