Subject: [PATCH 01/14] fsi: Move fsi_slave structure definition to header
Date:   Mon, 12 Jun 2023 14:56:44 -0500
Message-Id: <20230612195657.245125-2-eajames@linux.ibm.com>
In-Reply-To: <20230612195657.245125-1-eajames@linux.ibm.com>

Some FSI drivers may have need of the slave definition, so
move it to a header file. Also use one macro for obtaining a
pointer to the fsi_master structure.
