From 532db570e5181abc8f4f7bfa6c77c69ec2240198 Mon Sep 17 00:00:00 2001 From: Tony Prisk Date: Fri, 4 Jan 2013 15:35:47 -0800 Subject: drivers/rtc/rtc-vt8500.c: correct handling of CR_24H bitfield Control register bitfield for 12H/24H mode is handled incorrectly. Setting CR_24H actually enables 12H mode. This patch renames the define and changes the initialization code to correctly set 24H mode.
