[ Upstream commit fd748e177194ebcbbaf98df75152a30e08230cc6 ]
The of_device_unregister call in therm_windtunnel's module_exit procedure
does not fully reverse the effects of of_platform_device_create in the
module_init prodedure. Once you unload this module, it is impossible
to load it ever again since only the first of_platform_device_create
call on the fan node succeeds.
This driver predates first git commit, and it turns out back then
of_platform_device_create worked differently than it does today.
So this is actually an old regression.
The appropriate function to undo of_platform_device_create now appears
to be of_platform_device_destroy, and switching to use this makes it
possible to unload and load the module as expected.

[ Upstream commit d301a71c76ee4c384b4e03cdc320a55f5cf1df05 ]
The via-macii ADB driver calls request_irq() after disabling hard
interrupts. But disabling interrupts isn't necessary here because the
VIA shift register interrupt was masked during VIA1 initialization.
