I'm definitely not against it and I am sure that we all agree that this is a valid option for some drivers (certainly in embedded environments). But for me it has to stay an option. FYI: We allready have one driver that does this: w83697hf_wdt.c See commit 6fd656012bb8d5c5a4570adc2e630668b0109cb0.
Kind regards, Wim.
