Exists in smarc-l5.0.0_1.0.0-ga and in 5 other branches imx_3.10.17_1.0.1_ga, imx_3.10.53_1.1.0_ga, imx_3.14.28_1.0.0_ga, smarc-imx_3.10.53_1.1.0_ga, smarc-imx_3.14.28_1.0.0_ga

Input: atmel_mxt_ts - print less overhead when dumping objects 

Conserve limited (PAGE_SIZE) sysfs output buffer space by only showing
readable objects and not printing the object's index, which is not useful
to userspace.
