Subject: [PATCH 3/7] rpmsg: Update rpmsg_chrdev_register_device function
Date: Tue, 23 Mar 2021 13:27:33 +0100	[thread overview]
Message-ID: <20210323122737.23035-4-arnaud.pouliquen@foss.st.com> (raw)
In-Reply-To: <20210323122737.23035-1-arnaud.pouliquen@foss.st.com>

The rpmsg_chrdev driver has been replaced by the rpmsg_ctrl driver
for the /dev/rpmsg_ctrlX devices management. The reference for the
driver override is now the rpmsg_ctrl.

Update the rpmsg_chrdev_register_device function to reflect the update,
and rename the function to use the rpmsg_ctrldev prefix.

The platform drivers are updated accordingly.

Signed-off-by: Arnaud Pouliquen <arnaud.pouliquen@foss.st.com>
