Date: Sat, 28 Jan 2012 02:16:41 +0100 From: Wolfram Sang <w.sang@...gutronix.de> To: linux-kernel@...r.kernel.org Cc: Mark Brown <broonie@...nsource.wolfsonmicro.com>, Wolfram Sang <w.sang@...gutronix.de> Subject: [PATCH] regmap: Properly round reg_bytes and val_bytes For the upcoming 2/6-format, we don't see debugfs output otherwise, since the current division results in 0. I'd think 10/14 is broken currently, too.
