Subject: Re: [PATCH] watchdogs: fix several MODULE_PARM_DESC strings

Hi Randy,

Adding this one to the linux-2.6-watchdog-next tree.

I don't think it will build: WDT_TIMEOUT is the correct timeout macro.
I'll sent in a fix for this. Thanks!

This one is changed to:
+MODULE_PARM_DESC(io, MODNAME " I/O port (default: "
+                                       __MODULE_STRING(IO_DEFAULT) ").");

Kind regards,
Wim.
