Subject: [PATCH v8 12/22] PCI: microchip: Add num_events field to struct plda_pcie_rp
Date: Wed, 11 Oct 2023 19:05:04 +0800 [thread overview]
Message-ID: <20231011110514.107528-13-minda.chen@starfivetech.com> (raw)
In-Reply-To: <20231011110514.107528-1-minda.chen@starfivetech.com>
The event num is different in other platform. For re-use
interrupt process codes, replace with variable.
