Subject: [PATCH v2 03/10] PCI: designware-ep: Move the function of getting MSI capability forward
Date: Thu, 22 Aug 2019 19:22:35 +0800
Message-ID: <20190822112242.16309-3-xiaowei.bao@nxp.com> (raw)
In-Reply-To: <20190822112242.16309-1-xiaowei.bao@nxp.com>

Move the function of getting MSI capability to the front of init
function, because the init function of the EP platform driver will use
the return value by the function of getting MSI capability.
