Hi!
Until now it seems like the new cs46xx driver have been broken on SMP
machines, so with this patch it hopefully
work again. The only bad thing is that I dont have any SMP machine
(however I would like to have),
so I cant test it out.
This patch is reported to work at least by one SMP user. It would be
great if there any other SMP
owners with a cs46xx soudcard that would like to help testing the cs46xx
driver.
This patch included:
- Fix for a missplaced spin_lock: in cs46xx_playback_trigger(...)
spin_lock(..) was called twice,
first in cs46xx_playback_trigger(...) then in cs46xx_dsp_pcm_link(...)
causing a hang.
- Changed the "semaphore" aproach, I believe that it's easier solved now
and code is cleaner.
/Benny
