watchdog: sp805_wdt.c: use clk_prepare_enable and clk_disable_unprepare
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/) // <smpl> @@ expression e; @@ - clk_prepare(e); - clk_enable(e); + clk_prepare_enable(e); @@ expression e; @@ - clk_disable(e); - clk_unprepare(e); + clk_disable_unprepare(e); // </smpl> Signed-off-by: NJulia Lawall <Julia.Lawall@lip6.fr> Acked-by: NViresh Kumar <viresh.kumar@linaro.org> Signed-off-by: NWim Van Sebroeck <wim@iguana.be>
