Subject: [PATCH 1/4] Input: tsc2005 - improve readability of register defines
Date: Wed, 15 Jul 2015 14:13:25 +0200	[thread overview]
Message-ID: <1436962408-5206-2-git-send-email-sre@kernel.org> (raw)
In-Reply-To: <1436962408-5206-1-git-send-email-sre@kernel.org>

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.
