Subject: [PATCH v3 01/25] resource: Add a resource_list_first_type helper
Date: Mon, 28 Oct 2019 11:32:32 -0500 [thread overview]
Message-ID: <20191028163256.8004-2-robh@kernel.org> (raw)
In-Reply-To: <20191028163256.8004-1-robh@kernel.org>
A common pattern is looping over a resource_list just to get a matching
entry with a specific type. Add resource_list_first_type() helper which
implements this.
Signed-off-by: Rob Herring <robh@kernel.org>

- Rename resource_list_get_entry_of_type to resource_list_first_type
