Subject: dmaengine: intel_mid_dma: fix error status mask
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7f99a4216d68f6d75d5d544aa265d72f193bad7f;p=mv-sheeva.git

dmaengine: intel_mid_dma: fix error status mask

The error status mask (MASK_ERR) has the same format as the other
masks (MASK_TFR, MASK_BLOCK etc) and must be cleared the same way.
