Subject: [PATCH 4/4] platform/chrome: cros_ec_typec: Update mux flags during partner removal
Date: Mon, 7 Feb 2022 21:40:30 +0000 [thread overview]
Message-ID: <20220207214026.1526151-5-pmalani@chromium.org> (raw)
In-Reply-To: <20220207214026.1526151-1-pmalani@chromium.org>
In cros_typec_remove_partner(), we call
cros_typec_usb_disconnect_state() which sets the switches/muxes to be in
a disconnected state. This also happens in cros_typec_configure_mux().
However, unlike there, here the mux_flags variable hasn't been updated
to reflect that a disconnection has occurred. Update the flag here
accordingly.
