Subject: [PATCH 02/19] PCI: Set default bridge parent device
Date: Tue, 21 Jul 2020 20:24:57 -0600 [thread overview]
Message-ID: <20200722022514.1283916-3-robh@kernel.org> (raw)
In-Reply-To: <20200722022514.1283916-1-robh@kernel.org>
The host bridge's parent device is always the platform device. As we
already have a pointer to it in the devres functions, let's initialize
the parent device. Drivers can still override the parent if desired.
