Subject: [PATCH v2 01/25] resource: Add a resource_list_get_entry_of_type helper
Date: Wed, 16 Oct 2019 15:06:23 -0500 [thread overview]
Message-ID: <20191016200647.32050-2-robh@kernel.org> (raw)
In-Reply-To: <20191016200647.32050-1-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_get_entry_of_type() helper
which implements this.
