Subject: [PATCH 4.4 031/162] dmaengine: coh901318: Remove unused variable

From: Vinod Koul <vkoul@...nel.org>

commit 35faaf0df42d285b40f8a6310afbe096720f7758 upstream.

Commit 627469e4445b ("dmaengine: coh901318: Fix a double-lock bug") left
flags variable unused, so remove it to fix the warning.

drivers/dma/coh901318.c: In function 'coh901318_config':
drivers/dma/coh901318.c:1805:16: warning: unused variable 'flags' [-Wunused-variable]
  unsigned long flags;
                ^~~~~
