[Soekris] Heartbeat lost and no reboot on Soekris net4526 with 2.6 kernel

[Jakub Schmidtke]

Hi.

I had a problem with watchdog, which didn't want to reboot this device.

It said, that watchdog is enabled, then disabled, when I killed watchdog,
and after some time it said "Heartbeat lost, will not ping watchdog device".
And that was all, no reboot after that.

I have found a patch for sc520_wdt driver on Soekris FAQ:
http://www.seattlewireless.net/index.cgi/SoekrisFaq#head-86de7dfa18d77ec486fdfadb54ec9c21048ff94b
Patch: http://metrix.net/support/patches/kernel/soekris-sc520wd.diff

But it was for 2.4.19 kernel and I am using 2.6.12.5 kernel.
I have changed sc520_wdt driver in 2.6 kernel according to changes for 2.4 
kernel from this patch, and it started working correctly :)

So here is my patch, maybe someone else will find it useful :)
