From fec11bc0396bbd82b152e6ce9a47483ffd69462a Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Wed, 15 Nov 2017 17:38:52 -0800 Subject: mm/hmm: remove redundant variable align_end MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Variable align_end is assigned a value but it is never read, so the variable is redundant and can be removed.
