Subject: dmaengine: edma: Do not change the error code returned from edma_alloc_slot
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=04d537d95e2f48295b6f61ef7029a2dba75e3677;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

dmaengine: edma: Do not change the error code returned from edma_alloc_slot

In case of edma_alloc_slot() failure during probe we should return the error
unchanged to make debugging easier.
