Subject: mmc: mxs-mmc: Use devm_clk_get()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a5adbffda8d88a9e96c579b337b12cc8a6863575;p=linux-beck.git

mmc: mxs-mmc: Use devm_clk_get()

Using devm_clk_get() allows us to remove the clk_put() calls, so
let's use it to simplify the code.

Rename the 'out_clk_put' label to 'out_clk_disable' now that clk_put
is removed.
