Remove unnecessary initialization in notifier_block

Version 0.03 of wdt977.c - Changes that were made are:
* Extract the stop code in a seperate function (wdt977_stop)
* Extract the start code in a seperate function (wdt977_start)
* Rename kick_wdog to wdt977_keepalive for consistency
* Extract the watchdog's status code to a seperate function (wdt977_get_status)
* Change the way we deal with the watchdog timeout:
   Up till now we used timeoutM (in minutes) as the correct value and then
   calculated timeout as being timeoutM*60 or *timeoutM*120 (depending on
   wether or not we have the netwinder hardware bug).

   From now on timeout is the correct value and we calculate timeoutM out
   of it. Because of this we start with checking wether or not we have a
   correct timeout value (if not we reset it to the default value) and we
   automatically calculate timeoutM. Each time we change timeout with a
   correct timeout value, we recalculate timeoutM.
* Extended ioctl code with WDIOC_SETOPTIONS and updated the watchdog_info structure
* Added notifier support

Code has been tested by Woody

Two small fixes:
* Make cards_found a global variable so that if we remove the
  pci device we can count down.
* If we can't find a correct I/O address for the card, then we
should disable the card again.

* the scan-channels message seemed to always give invalid output.
  Look at the constant, and discover we are sending another
  message entirely.  Fix the constant (CARM_MSG_IOCTL).

* s/MISC_SYNC_TIME/MISC_SET_TIME/

* list some additional messages

* bump version number

* Not setting cb->skb = NULL after releasing skb to OS or during
  initialization of cbs.  Reported by Deepak Saxena

patch below adds bus_info for xirc2ps_cs; anaconda depends on this info to
be there.

This patch adds a helper function to initialize the debug bit mask
for use with netif_msg_*.  When the debug_value is out of range
it returns the default_msg_enable_bits.  Tested IA32.

This patch corrects the names of contributors of changes to the pcnet32
driver.

smctr_chk_mca() can be __init.

eepro_print_info() can be __init.

Andrew de Quincey added wol support to forcedeth.
The patch also renames additional function, to help analyzing backtraces.

The sense of the comparison was signed, but the code was testing
an unsigned variable for less-than-zero.
