Date: Sun, 13 Jan 2013 17:43:24 +0000 From: Ben Hutchings <ben@...adent.org.uk> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org Cc: akpm@...ux-foundation.org, alan@...rguk.ukuu.org.uk, Tony Prisk <linux@...sktech.co.nz>, Edgar Toernig <froese@....de>, Linus Torvalds <torvalds@...ux-foundation.org> Subject: [ 29/49] drivers/rtc/rtc-vt8500.c: correct handling of CR_24H bitfield 3.2-stable review patch. If anyone has any objections, please let me know. ------------------ From: Tony Prisk <linux@...sktech.co.nz> commit 532db570e5181abc8f4f7bfa6c77c69ec2240198 upstream. 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.
