Subject: [PATCH] scripts: checkpatch.pl

From: Raffaele Recalcati <raffaele.recalcati@...cino.it>

I've got a false positive when spaces are present
at the beginning of a line.
So I add this check, obviously outside comments.
This patch is compatible with the actual mainline,
I mean 7e27d6e778cd87b6f2415515d7127eba53fe5d02 commit.
