Subject: sh: tmu: Inline tmu_timer_{start,stop}()
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=15f11fc6d72175ff5b7763f03d7b0d502efd24af;p=u-boot.git

sh: tmu: Inline tmu_timer_{start,stop}()

These functions are always called for timer = 0, so drop the
timer check. Since these functions are called from one place
only and they are reduced to one line of code, just inline
them.
