[ALSA] Memory leak in sound/pcmcia/pdaudiocf/pdaudiocf.c
if one of the first three CS_CHECKS fails, we goto cs_failed: In this case parse we donr kfree() parse. Since the the last three CS_CHECKS might also fail, i moved the kfree() below all the CS_CHECKs and added one in the error path. This fixes coverity bug id #1099 Signed-off-by: Eric Sesterhenn <snakebyte@gmx.de> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
