From 828296debf7853752e47b6abfa608ab0172e53ec Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 4 Oct 2012 17:14:07 -0700 Subject: drivers/rtc/rtc-coh901331.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/) // @@ expression e; @@ - clk_prepare(e); - clk_enable(e); + clk_prepare_enable(e); @@ expression e; @@ - clk_disable(e); - clk_unprepare(e); + clk_disable_unprepare(e); // Signed-off-by: Julia Lawall Acked-by: Linus Walleij Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- drivers/rtc/rtc-coh901331.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'drivers/rtc/rtc-coh901331.c') diff --git a/drivers/rtc/rtc-coh901331.c b/drivers/rtc/rtc-coh901331.c index 76b2156d3c62..c8115b83e5ab 100644 --- a/drivers/rtc/rtc-coh901331.c +++ b/drivers/rtc/rtc-coh901331.c @@ -276,8 +276,7 @@ static void coh901331_shutdown(struct platform_device *pdev) clk_enable(rtap->clk); writel(0, rtap->virtbase + COH901331_IRQ_MASK); - clk_disable(rtap->clk); - clk_unprepare(rtap->clk); + clk_disable_unprepare(rtap->clk); } static struct platform_driver coh901331_driver = { -- cgit v1.2.3
