    Subjectw83781d i2c driver updated for 2.5.66 (without sysfs support)
    From
    Date
    Hi

    Ok, this is the w83781d driver updated for 2.5.66bk2. It works
    over here.

    I did look at the changes needed for sysfs, but this beast have
    about 6 ctl_tables, and is hairy in general. I am not sure what
    is the best way to do it for the different chips, so here is what
    I have until I or somebody else can do the sysfs stuff.


    Regards,
