Sorry this can be completely misleading, if read in conjunction with your sentences. Brevity in answers may disturb the message. It does not mean that you can and should force people to use that calibration... It means that users still can do per-device calibration and do not have to use the pre-calibration capability of the driver. Hence we called it pre-calibration. > > I just want to be able to do it the other way for those users who don't > care about this per-device variation. > > BR, > Nikolaus > > _______________________________________________ > http://projects.goldelico.com/p/gta04-kernel/ > Letux-kernel mailing list > Letux-kernel@xxxxxxxxxxxxxxx > http://lists.goldelico.com/mailman/listinfo.cgi/letux-kernel
