Subject: dmaengine: imx-sdma: Return a proper error code in platform_get_irq()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=63c72e028a1dd18515c356834d3f9cfce1cd3f51;p=linux-beck.git

dmaengine: imx-sdma: Return a proper error code in platform_get_irq()

There is no need to return a 'fake' value upon platform_get_irq() failure.

Just propagate the real error instead.
