[ARM PATCH] 2496/1: i.MX DMA fix
Patch from Sascha Hauer This patch fixes the handling of the dma interrupt acknowledge register (DISR). A DMA interrupt is acknowledged by setting the corresponding bit in DISR. So we are not allowed to use |= on this register because we could lose interrupts. Sascha Hauer Signed-off-by: Sascha Hauer Signed-off-by: Russell King
