Subject: [PATCH 1/9] cdrom/gdrom: add error handling support for add_disk()
Date: Thu, 2 Sep 2021 10:40:57 -0700 [thread overview]
Message-ID: <20210902174105.2418771-2-mcgrof@kernel.org> (raw)
In-Reply-To: <20210902174105.2418771-1-mcgrof@kernel.org>
We never checked for errors on add_disk() as this function
returned void. Now that this is fixed, use the shiny new
error handling.
