Subject: [PATCH v1 3/9] PCI: microchip: Enable event handlers to access bridge and ctrl ptrs
Date: Wed, 16 Nov 2022 13:54:58 +0000	[thread overview]
Message-ID: <20221116135504.258687-4-daire.mcnamara@microchip.com> (raw)
In-Reply-To: <20221116135504.258687-1-daire.mcnamara@microchip.com>

From: Daire McNamara <daire.mcnamara@microchip.com>

Minor re-organisation so that event handlers can access both a pointer
to the bridge area of the PCIe rootport and the ctrl area of the PCIe
rootport.
