Subject: [PATCH 03/24] part: dos: Use desc instead of dev_desc
Date: Sun, 13 Aug 2023 08:26:31 -0600	[thread overview]
Message-ID: <20230813142708.361456-4-sjg@chromium.org> (raw)
In-Reply-To: <20230813142708.361456-1-sjg@chromium.org>

The dev_ prefix is a hangover from the pre-driver model days. The device
is now a different thing, with driver model. Update the dos code to
just use 'desc'.
