No, don't make a new kconfig option for something that everyone has to enable as they don't know what they have on their system (think universal kernels built by distros.) Do this check dynamically, depending on the chip the driver is running on, don't rely on a user to know what to do here. So I'm not going to accept this patch, sorry. greg k-h _______________________________________________ devel mailing list [email protected] http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
