drivers/rtc/rtc-coh901331.c: use clk_prepare_enable() and clk_disable_unprepare()
Author: Julia Lawall <Julia.Lawall@lip6.fr>
clk_prepare_enable and clk_disable_unprepare combine clk_prepare and
clk_enable, and clk_disable and clk_unprepare. They make the code more
concise, and ensure that clk_unprepare is called when clk_enable fails.
A simplified version of the semantic patch that introduces calls to these
functions is as follows: (http://coccinelle.lip6.fr/)
//
@@
expression e;
@@
- clk_prepare(e);
- clk_enable(e);
+ clk_prepare_enable(e);
@@
expression e;
@@
- clk_disable(e);
- clk_unprepare(e);
+ clk_disable_unprepare(e);
