[ALSA] PCM resume cleanups
Jaroslav Kysela [Thu, 18 Aug 2005 11:43:12 +0000 (13:43 +0200)]
Digigram VX core,CS4231 driver,ATIIXP driver,VIA82xx driver
VIA82xx-modem driver,au88x0 driver,CS46xx driver,Trident driver
This patch disables SNDRV_PCM_INFO_RESUME flag for drivers which does not
support the full resume.
