checkpatch: improve SUSPECT_CODE_INDENT test
Many lines exist like if (foo) bar; where the tabbed indentation of the branch is not one more than the "if" line above it. checkpatch should emit a warning on those lines. Miscellenea: o Remove comments from branch blocks o Skip blank lines in block Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
