Subject: [PATCH 09/10] serial: Make uart_handle_cts_change() status param bool
Date: Wed, 4 Jan 2023 17:15:30 +0200 [thread overview]
Message-ID: <20230104151531.73994-10-ilpo.jarvinen@linux.intel.com> (raw)
In-Reply-To: <20230104151531.73994-1-ilpo.jarvinen@linux.intel.com>
Convert uart_handle_cts_change() to bool which is more appropriate
than unsigned int.
Cleanup callsites from operations that are not necessary with bool.
