Subject: drivers/video/backlight/max8925_bl.c: drop devm_kfree of devm_kzalloc'd data
X-Git-Tag: upstream/snapshot3+hdmi~6031^2~127
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2c114cb4edb741822ea48e80be8c525032206e9a;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

drivers/video/backlight/max8925_bl.c: drop devm_kfree of devm_kzalloc'd data

devm_kfree() allocates memory that is released when a driver detaches.
Thus, there is no reason to explicitly call devm_kfree in probe or remove
functions.
