Since we have a bitwise definition of snd_pcm_state_t and use it for
certain struct fields, a few new (and years old) sparse warnings came
up. This patch is an attempt to cover them.
- The state fields in snd_pcm_mmap_status* and co are all defined as
snd_pcm_state_t type now
- The PCM action callbacks take snd_pcm_state_t argument as well;
some actions taking special values got the explicit cast and
comments
- For the PCM action that doesn't need an extra argument receives
ACTION_ARG_IGNORE instead of ambiguous 0
While we're at it, the boolean argument is also properly changed to
bool and true/false, as well as a slight refactoring of PCM pause
helper function to make easier to read.
No functional changes, just shutting up chatty sparse.
