From c212acccc368a087a53559aac2b7d3be941b1252 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Sat, 28 Jan 2012 02:16:41 +0100 Subject: 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.
