  SVN rev 201882 on 2010-01-09 04:00:22Z by keramida
  
  Revert iwn channel-argument handling of set_txpower() to r201822
  
  Pass the channel argument as a real argument and not through
  RXON.  The RXON version seems to have problem with both the older
  228.57.2.23 firmware and the latest 228.61.2.24 version resulting
  in device initialization errors like:
  
    wpa_supplicant[2928]: Failed to initiate AP scan.
    kernel: firmware error log:
    kernel: error type      = "SYSASSERT" (0x00000005)
    kernel: program counter = 0x0000147C
    kernel: source line     = 0x0000058B
    kernel: error data      = 0x0000058B00000000
    kernel: branch link     = 0x0000145A00001492
    kernel: interrupt link  = 0x000006DE00000000
    kernel: time            = 7310
    ...
    kernel: iwn0: iwn_config: could not set TX power
    kernel: iwn0: iwn_init_locked: could not configure device, error 35
  
  By passing the current channel to hal->set_txpower() the firmware
  error is fixed, at least for the 4965 chipset of my Thinkpad and
  the ones tested by Bernhard.
