Subject: [PATCH 2/3] remoteproc: core: Move validate before device add
Date: Mon, 17 May 2021 13:45:48 -0700	[thread overview]
Message-ID: <1621284349-22752-3-git-send-email-sidgup@codeaurora.org> (raw)
In-Reply-To: <1621284349-22752-1-git-send-email-sidgup@codeaurora.org>

We can validate whether the remoteproc is correctly setup before
calling making the cdev_add and device_add calls. This saves us
the trouble of cleaning up later on.
