mwifiex: fix system freeze while reloading driver Unload sequence for mwifiex PCIE driver is as follows: 1. Invoking cleanup module from kernel results into pci_unregister_driver 2. Kernel invokes PCIE remove() handler which disconnects all interfaces. 3. One step during disconnect is to clean PCIE TX rings. During this we read txbd_rdptr from FW. While loading driver next time, we see pci_enable_device() results into system freeze. This may have happened because we accessed PCI device after unregistering from bus driver. Removing this ioread() operation resolves this bug. Signed-off-by: Avinash Patil <patila@marvell.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: John W.
