No the linux kernel CONFIG_TOUCHSCREEN_ADS7846=m buills only the
'basic' ads7846.ko kernel module. You need the additional
ads7846_device.ko kernel module which will configure your basic
ads7846.ko module. Therefore the buildroot patch which will
build the ads7846_device.ko module for you (and will do the
right kernel config additions)....

Regards,
Peter
