[PATCH 08/23 v6] Input: atmel_mxt_ts - print less overhead when dumping objects

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
