Ok, I need a bit of Kconfig help for drivers/i2c/chips to set CONFIG_I2C_SENSOR to be "y" if either of those two drivers are selected as "y". Anyone know how?

thanks,

greg k-h

The following (untested) should work:

config I2C_SENSOR

        tristate
        default y if SENSORS_ADM1021=y || SENSORS_LM75=y || SENSORS_VIA686A=y   || SENSORS_W83781D=y
        default m if SENSORS_ADM1021=m || SENSORS_LM75=m || SENSORS_VIA686A=m   || SENSORS_W83781D=m
        default n

        of the darkness. There had been need of rain for many days.
       "Only a promise," Lao Er said.

Thanks, that worked out great. I'll make up a patch and send it on.
