[PATCH] mm/hmm: remove redundant variable align_end

From: Colin King
Date: Tue Oct 17 2017 - 10:38:46 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Variable align_end is assigned a value but it is never read, so
the variable is redundant and can be removed. Cleans up the clang
warning: Value stored to 'align_end' is never read
