Subject: [PATCH v2 07/16] rpmsg: char: clean up rpmsg class
Date: Tue, 22 Dec 2020 11:57:17 +0100 [thread overview]
Message-ID: <20201222105726.16906-8-arnaud.pouliquen@foss.st.com> (raw)
In-Reply-To: <20201222105726.16906-1-arnaud.pouliquen@foss.st.com>
Suppress the management of the rpmsg class as attribute. It is already
handled in /sys/bus rpmsg as specified in
documentation/ABI/testing/sysfs-bus-rpmsg.
This patch prepares the migration of the control device in rpmsg_ctrl.
