From f9c22736940cdc8f5e2db0109fc9493e0cbd895d Mon Sep 17 00:00:00 2001 From: "Hans J. Koch" Date: Sun, 12 Jul 2009 20:51:25 -0700 Subject: Input: ucb1400_ts - fix a misleading function name The driver for UCB1400 touchscreen controllers contains a function named ucb1400_ts_pen_down(), but it returns 0 if the pen is down and 1 if it's up. This causes confusion, especially since it's used as a boolean truth value later in the code. This patch renames it. Signed-off-by: Hans J.
