4433248bf3 remove superfluous free() checks 
free() correctly handles NULL pointers, so we can omit explicit checks
for that condition.

33a40df1af Fix the handling of stereo capture source 
Patch from bug#1610

The simple mixer doesn't handle the stereo "Capture Source" properly,
wrongly set cswitch-joined.

ce67d5389b more simple mixer - basic abstraction - work 
- midlayer cleanups and simplification
- probably broke the "none" abstraction code somehow (not intensively tested
  midlayer changes)
- trying to implement ac97 module
  - far from finished
  - common code should be moved to alsa-lib as core for other modules
  - perhaps simple_abst.c can be based on this common code, too

597b4d0942 big simple mixer update 
- exported all necessary functions to create a mixer module outside alsa-lib
- separated simple mixer API from the simple mixer implementation
  (using callbacks as usuall)
  - src/mixer/simple.c is the core
  - src/mixer/simple_none.c is the current (no-abstraction) implementation
    based on control names; note that this module does not depend on
    internal ALSA structures now
  - src/mixer/simple_abst.c is the ongoing abstraction which will use
    external dynamic modules; src/conf/smixer.conf will describe which
    modules will be used depending on the components from the driver
