Andreas Pape 6a95642541 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.
