From: Ryder Lee Date: Wed, 4 Nov 2020 20:58:33 +0000 (+0800) Subject: PCI: mediatek: Configure FC and FTS for functions other than 0 X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=31ec9c2746467a372b009940ce7b722055daaf6a;p=linux.git PCI: mediatek: Configure FC and FTS for functions other than 0 "PCI_FUNC(port->slot << 3)" is always 0, so previously mtk_pcie_startup_port() only configured FC credits and FTs for function 0. Compute "func" correctly so we also configure functions other than 0. This affects MT2701 and MT7623.
