From 511c674cd6c16067cb0a922d1d29a5e4a04967e8 Mon Sep 17 00:00:00 2001
From: Andreas Sandberg <andreas.sandberg@arm.com>

Subject: [PATCH] style: Remove unsupported style.py commands

Remove the unsupported style.py subcommands (fixwhite, chkwhite),
which leaves the chkformat command as the only remaining
command. Since the script now only supports one command, remove the
sub-command support altogether.
