Date: Wed, 22 Jul 2015 22:04:41 +0200 From: Sebastian Reichel <sre@...nel.org> To: Dmitry Torokhov <dmitry.torokhov@...il.com>, linux-input@...r.kernel.org Cc: Michael Welling <mwelling@...cinc.com>, linux-omap@...r.kernel.org, linux-kernel@...r.kernel.org, Sebastian Reichel <sre@...nel.org> Subject: [PATCH 1/5] Input: tsc2005 - improve readability of register defines Improve defines for first control byte by removing 0x00 prefix (the defines are for 8 bit values and not for 16 bit values) and expose register structure by exposing the shift.
