From 6b4c5bebcebb0a48d29947e9aa749650751a7696 Mon Sep 17 00:00:00 2001 From: Andy Whitcroft Date: Tue, 26 Oct 2010 14:23:11 -0700 Subject: [PATCH] checkpatch: fix regressions in "fix handling of leading spaces" The patch "checkpatch: fix handling of leading spaces" added checks for leading spaces on lines, but this introduces regressions. Firstly it does not correctly detect when we are in a comment. Secondly it does not allow for preprocessor command spacing. Finally it does not allow for label indentation which is required to be less than one tab.
