ALSA: ALSA: ctxfi - Release PCM resources at each prepare call
The prepare callback can be called multiple times, thus it needs to release and acquire the resource again by itself at the second or later call. Simply add pcm_release_resources() at the beginning of each prepare callback in ctatc.c. Signed-off-by: Takashi Iwai <tiwai@suse.de>
