From mboxrd@z Thu Jan 1 00:00:00 1970 From: Kishon Vijay Abraham I Subject: [PATCH 12/15] PCI: cadence: Remove pci_epf_linkup from Cadence EP driver Date: Mon, 7 Jan 2019 12:11:45 +0530 Message-ID: <20190107064148.10152-13-kishon@ti.com> References: <20190107064148.10152-1-kishon@ti.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: In-Reply-To: <20190107064148.10152-1-kishon@ti.com> Sender: linux-kernel-owner@vger.kernel.org To: Lorenzo Pieralisi , Bjorn Helgaas , Gustavo Pimentel , Alan Douglas , Shawn Lin Cc: Jingoo Han , Heiko Stuebner , Cyrille Pitchen , Jia-Ju Bai , linux-omap@vger.kernel.org, linux-pci@vger.kernel.org, linux-kernel@vger.kernel.org, linux-rockchip@lists.infradead.org, linux-arm-kernel@lists.infradead.org, kishon@ti.com List-Id: linux-omap@vger.kernel.org pci_epf_linkup is intended to be invoked if the EPC supports linkup notification. Now that pci-epf-test uses get_features callback, which indicates Cadence EP driver doesn't support linkup notification, remove pci_epf_linkup from Cadence EP driver.
