From a5ee351d5bc7c9e0abdbc3d345a503cc07d0623f Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Thu, 8 Aug 2019 16:02:43 -0700 Subject: Input: bu21013_ts - remove useless comments The comments for individual functions in the driver do not provide any additional information beyond what function names indicate.
