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.
