From 8855f30cd2b68012571932c7b01290c20be4508c Mon Sep 17 00:00:00 2001 From: Tatsunosuke Tobita Date: Tue, 18 Jun 2013 23:13:28 -0700 Subject: Input: wacom_i2c - implement hovering capability Although BTN_TOOL_PEN and BTN_TOOL_RUBBER functioned properly, the driver didn't have hover functionality, so it's been added. Also, "WACOM_RETRY_CNT" was not used, so it was removed.
