[iwlwifi] Timeout waiting for hardware access (CSR_GP_CNTRL 0xffffffff)

[Chris J Arges]

Was using wireless on my x220 thinkpad, took it out of the dock and wireless stopped working. I couldn't remove and re-insert iwlwifi to get this working. I had to do a complete reboot of the system before wireless worked again.
