Andreas Pape 6621f2964c ALSA: dmaengine: increment buffer pointer atomically ...

[ Upstream commit d1c4420195 ]

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.
