From 654c192a72ffa7e415a9f58a4f4c5f4368b754e7 Mon Sep 17 00:00:00 2001 From: Ping Cheng Date: Tue, 3 Oct 2017 15:05:41 -0700 Subject: HID: hid-input: Add eraser usage to hidinput_configure_usage Some tablets report eraser usage to indicate the eraser tool tip is touching the surface. But, hidinput_configure_usage didn't support the usage, which led it falls into default as ABS_MISC.
