Subject: [RFC 10/12] block/ataflop add error handling support for add_disk()
Date: Thu, 15 Jul 2021 13:59:18 -0700 [thread overview]
Message-ID: <20210715205920.2023980-11-mcgrof@kernel.org> (raw)
In-Reply-To: <20210715205920.2023980-1-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.
We reuse the atari_floppy_disk_remove() call.
