Hmm, that is really shame :-/ My test setup triggered "Trying to free
nonexistent resource" warning, but dissasembly of lib/devres.o shows
no call to devres_destroy, which seems that WARN_ON in
__devm_release_region() is optimized out. Strange. So far sorry
for the noise, I'll try figure out what broke after weekend.
