Subject: omap hsmmc: fix processing of all dma interrupts as block completion
From: Venkatraman S <svenkatr@xxxxxx>
If other informative interrupts are enabled for the DMA channel used by
hsmmc, those are incorrectly treated as block completion. This patch lets
only the block completion interrupt to be processed.
