Subject: [PATCH 1/4] platform/chrome: cros_ec_typec: Move mux flag checks
Date: Mon,  7 Feb 2022 21:40:24 +0000	[thread overview]
Message-ID: <20220207214026.1526151-2-pmalani@chromium.org> (raw)
In-Reply-To: <20220207214026.1526151-1-pmalani@chromium.org>

Move mux and role flag checks inside of cros_typec_configure_mux(),
which is a more logical location for them.
