Update of /cvsroot/alsa/alsa-kernel/include
In directory sc8-pr-cvs1:/tmp/cvs-serv14205/include
Modified Files:
pcm.h
Log Message:
[PATCH: pcm-memory-fix.dif]
- added UNKNOWN type for dma_type, set as default to check invalid
uses of pre-allocated data.
- clean up the pre-allocation code, added more comments.
- call snd_pcm_lib_preallocate_free_fo_all() in the destructor of
pcm instance, to be sure to release all the buffers.
now, each pcm driver doesn't have to call preallocate_free_*() in
its private_free callback.
