Subject: [PATCH v4 01/19] spi: move `cs_change_delay` backwards compat logic outside switch
Date: Thu, 26 Sep 2019 13:51:29 +0300 [thread overview]
Message-ID: <20190926105147.7839-2-alexandru.ardelean@analog.com> (raw)
In-Reply-To: <20190926105147.7839-1-alexandru.ardelean@analog.com>
The `cs_change_delay` backwards compatibility value could be moved outside
of the switch statement.
The only reason to do it, is to make the next patches easier to diff.
