Takashi Iwai 4be05b0a7e ALSA: ali5451: Fix out-of-bound position reporting 
commit db68577966abc1aeae4ec597b3dcfa0d56e92041 upstream.

The pointer callbacks of ali5451 driver may return the value at the
boundary occasionally, and it results in the kernel warning like
  snd_ali5451 0000:00:06.0: BUG: , pos = 16384, buffer size = 16384, period size = 1024

It seems that folding the position offset is enough for fixing the
warning and no ill-effect has been seen by that.
