I have reviewed some old changes in (now obsoleted) lk-2-4 branch of i2c sources. I believe, that in the process of <2.4 cleanup, reference counting for modules is completely lost. That is, one may call rmmod to remove either a sensor client or its adapter module, while one of its sysctl's (file/dir under /proc/sys/dev/sensors/) is open. Even i2c release 2.7.0 counts for client usage only. As adapter removal will detach the client as well, I am not convinced this is enough. I do not know if sysfs handles this correctly? -- Ky?sti M?lkki <kyosti.malkki at welho.com> +358 50 462 8786
