[PATCH] i810 watchdog driver: support for i815/i8[2456]0 chipsets

[<pazke@orbita1.ru>]

[-- Attachment #1: Type: text/plain, Size: 379 bytes --]

Hi all,

this small patch (2.4.5-ac16) adds Intel i815/i820/i840/i850/i860 chipsets support
into i810 TCO watchdog driver, also MODULE_DEVICE_TABLE added.

Should work but untested (can't stop server just to test it :)

Best regards.
