Subject: [PATCH] checkpatch: do not test/warn of leading whitespace before signature tags

From: Bruce Allan <bruce.w.allan@...el.com>

Commit 2011247 introduced additional style checks for signature tags in
patches which is good.  Unfortunately, now whenever patches are checked
by piping the output of 'git show' or 'stg show' through checkpatch it
warns not to use whitespace before all signature tags since these (and the
rest of the patch description) are indented.  Remove this test/warning.
