Andy and Guenter, I presume the two of you discussed how this patch would get
submitted as I see the following in the platform driver x86 for-next branch:

    Acked-by: Guenter Roeck <linux@...ck-us.net>
    Signed-off-by: Andy Shevchenko <andriy.shevchenko@...ux.intel.com>

for both:

140c91b2 watchdog: iTCO_wdt: Add PMC specific noreboot update api
f583a88 watchdog: iTCO_wdt: cleanup set/unset no_reboot_bit functions

This suggests these were deliberately added to our tree and not accidentally
included through a rebase without --preserve-merges or something like that.

Guenter, if you prefer/need to submit this through your tree, can you provide
us with an immutable branch to merge for the dependencies of our later patches?
If you can drop these two patches without a dependency problem in your tree,
that would be the cleanest solution as we could avoid an additional merge.

Thanks,

Darren
