Subject: [PATCH 7/7] carma: remove unnecessary DMA_INTERRUPT capability
=20
From: "Ira W. Snyder" <redacted>
=20
These drivers set the DMA_INTERRUPT capability bit when requesting a DMA
controller channel. This was historical, and is no longer needed.
=20
Recent changes to the drivers/dma/fsldma.c driver have removed support
for this flag. This makes the carma drivers unable to find a DMA channel
with the required capabilities.
