dmaengine: axi-dmac: Propagate errors from platform_get_irq()
Propagate errors returned by platform_get_irq() to the driver core. This will enable proper probe deferring for the driver in case the IRQ provider has not been registered yet. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
