Subject: dma: mv_xor: Remove unneeded NULL address check
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a911ddc9a0ecbf77a8b2e78dc5c40e5b7bb40d24;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

dma: mv_xor: Remove unneeded NULL address check

This mmio address is checked at probe-time, which makes this test
redundant. Let's just remove it.
