Subject: dma/intel_mid_dma: remove unneeded null check
X-Git-Tag: MMI-PSA29.97-13-9~20995^2~12^3~1
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=66bde0b70aa2e348ac2c9b9626743c1402b9d466;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git

dma/intel_mid_dma: remove unneeded null check

Smatch complains because we dereference "mid" before checking it.  It
turns out that "mid" is always a valid pointer here so we can just
remove the check.
