From: Daniel Glöckner Date: Wed, 3 Aug 2011 23:21:02 +0000 (-0700) Subject: rtc-omap: fix initialization of control register X-Git-Tag: v3.1-rc1~76 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=12b3e038e5bb4860c17d001e92a6fa9964c0a7b9;p=platform%2Fkernel%2Flinux-3.10.git rtc-omap: fix initialization of control register As the comment explains, the intention of the code is to clear the OMAP_RTC_CTRL_MODE_12_24 bit, but instead it only clears the OMAP_RTC_CTRL_SPLIT and OMAP_RTC_CTRL_AUTO_COMP bits, which should be kept. OMAP_RTC_CTRL_DISABLE, OMAP_RTC_CTRL_SET_32_COUNTER, OMAP_RTC_CTRL_TEST, and OMAP_RTC_CTRL_ROUND_30S are also better off being cleared.
