Andreas Pape b14dc26227 ALSA: dmaengine: increment buffer pointer atomically 
[ Upstream commit d1c442019594692c64a70a86ad88eb5b6db92216 ]

Setting pointer and afterwards checking for wraparound leads
to the possibility of returning the inconsistent pointer position.

This patch increments buffer pointer atomically to avoid this issue.

Fixes: e7f73a1613 ("ASoC: Add dmaengine PCM helper functions")
