Subject: [PATCH v4 4/9] driver core: Let dev_of_node() accept a NULL dev
Date: Fri, 12 Apr 2019 11:31:45 -0700	[thread overview]
Message-ID: <20190412183150.102131-5-sboyd@kernel.org> (raw)
In-Reply-To: <20190412183150.102131-1-sboyd@kernel.org>

We'd like to chain this in places where the 'dev' argument might be
NULL. Let this function take a NULL 'dev' so this can work.
