Subject: sata_mv: Delete unnecessary checks before the function call "phy_power_off"
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=fad06016433bb1e890ce7d170079351099518489;p=linux-beck.git

sata_mv: Delete unnecessary checks before the function call "phy_power_off"

The phy_power_off() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
