From b53c8e104ed071c47ada2adce194625ab03d9f3d Mon Sep 17 00:00:00 2001 From: Andy Whitcroft Date: Tue, 6 Jan 2009 14:41:29 -0800 Subject: checkpatch: ensure we actually detect if assignments split across lines When checking for assignments within if conditionals we check the whole of the condition, but the match is performed using a line constrained regular expression. This means we can miss split conditionals or those on the second line. Allow the check to span lines.
