Subject: [PATCH 02/60] mtd: core: set some defaults when dev.parent is set
Date: Tue,  3 Mar 2015 22:39:46 +0100	[thread overview]
Message-ID: <1425418844-25177-3-git-send-email-fransklaver@gmail.com> (raw)
In-Reply-To: <1425418844-25177-1-git-send-email-fransklaver@gmail.com>

If a parent device is set, add_mtd_device() has enough knowledge to fill
in some sane default values for the module name and owner. Do so if they
aren't already set.
