Subject: ALSA: au88x0: Fix calculation in vortex_wtdma_bufshift()
From: Takashi Iwai <[email protected]>
commit 62db7152c924e4c060e42b34a69cd39658e8a0dc upstream.
vortex_wtdma_bufshift() function does calculate the page index wrongly, first masking then shift, which always results in zero. The proper computation is to first shift, then mask.
