[PATCH v2 2/9] dmaengine: edma: Use enum for eDMA binding type (legacy vs TPCC)

From: Peter Ujfalusi
Date: Wed Sep 21 2016 - 06:29:57 EST


Fixes the following warning when compiling the driver for 64bit
architectures (x86_64 for example):
drivers/dma/edma.c:2185:16: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
if (match && (u32)match->data == EDMA_BINDING_TPCC)
^
