When the card is not owned by the PCIe bus, we need to acquire ownership first. This flow is implemented in iwl_pcie_prepare_card_hw. Because of a hardware bug, we need to disable link power management before we can request ownership otherwise the other user of the device won't get notified that we are requesting the device which will prevent us from acquire ownership. Same holds for the down flow where we need to make sure that any other potential user is notified that the driver is going down. CC: <stable@vger.kernel.org> [4.1] Signed-off-by:
