SubjectRe: I/O collisions w/ hwmon/it87.c and watchdog/it8712f_wdt.c? (Super I/O chips in general..)
Does it make sense to use the drivers/mfd directory for Super I/O
chips then? Is there any problem with having other hwmon, watchdog,
etc depend on drivers/mfd? Should this kind of setup for platform
devices be documented in the driver-model?
