Andreas Pape 93c8628183 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.
