Hi Linus,

Please pull from 'master' branch of
	git://www.linux-watchdog.org/linux-watchdog.git

It will make sure that the hpwdt driver will not load auxilary iLO devices.

This will update the following files:

    watchdog: hpwdt: Patch to ignore auxilary iLO devices
    
    This patch is to prevent hpwdt from loading on any auxilary iLO devices defined
    after the initial (or main) iLO device. All auxilary iLO devices will have a
    subsystem device ID set to 0x1979 in order for hpwdt to differentiate between
    the two types.

For completeness, I added the overal diff below.

Greetings,
