From f61c890ec631884c5b7cd8723cd8ae1917dca544 Mon Sep 17 00:00:00 2001 From: Shine Liu Date: Thu, 20 Aug 2009 23:02:23 +0800 Subject: [PATCH] ASoC: S3C24XX : Align the peroid size to the buffer size > Then it's a driver bug. If unaligned period size is allowed, it means > that the irq is really generated in that period, not at the buffer > boundary. Otherwise, it must have a proper hw-constraint to align the > period size to the buffer size. This patch will fix the bug metioned in the above mail. Force the peroid size to be aligned with the buffer size. Based and tested on linux-2.6.31-rc6.
