From c3f27a26b477baf8e32848731e860618e5f48b58 Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Wed, 2 Jul 2014 11:22:10 +0100 Subject: [PATCH] mfd: ab8500-debugfs: Simplify invalid debugfs data checking Noticed during a coding review, if we reorganised the checking a little, we can rid the code of a pointless 'else'. Whilst looking for this particular code hunk I noticed another pointless 'else', which I've subsequently fixed in this patch.
