Subject: [PATCH v4 2/4] remoteproc: core: Move validate before device add
Date: Tue, 15 Jun 2021 12:03:42 -0700 [thread overview]
Message-ID: <1623783824-13395-3-git-send-email-sidgup@codeaurora.org> (raw)
In-Reply-To: <1623783824-13395-1-git-send-email-sidgup@codeaurora.org>
We can validate whether the remoteproc is correctly setup before
making the cdev_add and device_add calls. This saves us the
trouble of cleaning up later on.
