Date: Tue, 05 Mar 2013 14:58:53 +0800 From: Axel Lin <axel.lin@...ics.com> To: Linus Walleij <linus.walleij@...aro.org> Cc: Lee Jones <lee.jones@...aro.org>, linux-kernel@...r.kernel.org Subject: [PATCH RFT] pinctrl: abx500: Fix checking if pin use AlternateFunction register It's pointless to check "af.alt_bit1 == UNUSED" twice. This looks like a copy-paste bug, I think what we want is to check if *both* af.alt_bit1 and af.alt_bit2 are UNUSED. Signed-off-by: Axel Lin <axel.lin@...ics.com> --- Hi, I don't have the datasheet and hw. I'd appreciate if someone can review and test this patch.
