Date: Mon, 31 Dec 2012 07:56:33 +1300 From: Tony Prisk <linux@...sktech.co.nz> To: Alessandro Zummo <a.zummo@...ertech.it> Cc: linux-kernel@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, vt8500-wm8505-linux-kernel@...glegroups.com, rtc-linux@...glegroups.com, Tony Prisk <linux@...sktech.co.nz>, Edgar Toernig <froese@....de> Subject: [PATCH] rtc: vt8500: Fix year field in vt8500_rtc_set_time year field is incorrectly masked when setting the date. If the year is beyond 2099, the year field will be incorrectly updated in hardware. This patch masks the year field correctly.
