IIRC the size of an enum is implementation defined, so this could still fail sometimes. I tend to use 'uintptr_t' for the cast instead.

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) ^ Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> --- drivers/dma/edma.c | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-)
