Subject: [PATCH v2 4/5] serial: sunsab: Remove frame size calculation dead-code
Date: Tue, 30 Aug 2022 11:49:24 +0300	[thread overview]
Message-ID: <20220830084925.5608-5-ilpo.jarvinen@linux.intel.com> (raw)
In-Reply-To: <20220830084925.5608-1-ilpo.jarvinen@linux.intel.com>

The driver features a custom frame length calculation but the result is
never used. Remove it.
