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. Fix these up: Signed-off-by: Andy Whitcroft <apw@canonical.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
