Hi Jean, All, Updating lm78 driver, now that it has sole ownership of its ISA ioports ;) Busy locking: commentary states it may deadlock? Is not avoiding collisions between ISA and SMBus as per datasheet desirable? Anything else I should know while updating this old driver? Plans: whitespace / cleanup convert to dynamic sysfs add auto-fan-div ?? (perhaps a final cleanup) Thanks, Grant.
