is the plan to land these two patches via Guenter's watchdog tree [0]?
[0] git://www.linux-watchdog.org/linux-watchdog.git
In fact, though, I don't see any new patches in that repository.
The only branches I see are:
remotes/wdog/master b953c0d Linux 4.1
remotes/wdog/winbond-superio dc89871
Sample Winbond Super-I/O MFD device consisting out of a lowel-level
driver that does the detection and creates the platform-data and a
watchdog driver.
Am I looking in the wrong place?
