Date: Sat, 19 Nov 2016 00:32:46 -0800 Message-Id: <1479544367-7195-3-git-send-email-ashok.raj@intel.com> In-Reply-To: <1479544367-7195-1-git-send-email-ashok.raj@intel.com> References: <1479544367-7195-1-git-send-email-ashok.raj@intel.com> Sender: linux-pci-owner@vger.kernel.org List-ID: If an error occurs enabling a slot on a hot plug event, the presence LED is disabled. It is not an error, though, when the slot was already enabled. This patch returns success if called to enable an already enabled slot. This is in the same spirit of the special handling for EEXISTS when pciehp_configure_device determines the slot devices already exist.
