Subject: mfd: 88pm860x: Drop devm_kfree of devm_kzalloc'd data
X-Git-Tag: firefly_0821_release~3680^2~568^2~58
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=85529575b67c318e296ae183cc80617d79aea23b;p=firefly-linux-kernel-4.4.55.git

mfd: 88pm860x: 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.
