[PATCH] ALSA: core: Call substream ack() method upon compat mmap, commit

[Alan Young]

   If a 32-bit application is being used with a 64-bit kernel and is using
   the mmap mechanism to write data, then the SNDRV_PCM_IOCTL_SYNC_PTR
   ioctl results in calling snd_pcm_ioctl_sync_ptr_compat(). Make this use
   pcm_lib_apply_appl_ptr() so that the substream's ack() method, if
   defined, is called.
   The snd_pcm_sync_ptr() function, used in the 64-bit ioctl case, already
   uses snd_pcm_ioctl_sync_ptr_compat().
