This patch fixes the following bug: usb 1-1.1: restart device (8) BUG: sleeping function called from invalid context at drivers/usb/core/urb.c:654 in_atomic(): 1, irqs_disabled(): 0, pid: 0, name: swapper (usb_poison_urb+0x1c/0xf8) (usb_poison_anchored_urbs+0x48/0x78) (carl9170_usb_handle_tx_err+0x128/0x150) (carl9170_usb_reset+0xc/0x20) (carl9170_handle_command_response+0x298/0xea8) (carl9170_usb_tasklet+0x68/0x184) (tasklet_hi_action+0x84/0xdc) this only happens if the device is plugged in an USB port, the driver is loaded but inactive (e.g. the wlan interface is down). If the device is active everything is fine. Signed-off-by: NRonald Wahl <ronald.wahl@raritan.com> Signed-off-by: NChristian Lamparter <chunkeey@googlemail.com> Signed-off-by: NJohn W.
