[PATCH 18/63] dmaengine: ste_dma40: Remove 'always true' checking

From: Lee Jones
Date: Fri May 03 2013 - 10:46:44 EST


Before allocating memory for logical channels, the current driver
checks to see if there are any. Well as the dma40_memcpy_channels[]
array is always populated, the check is always true. Best to
remove the check.
