From 48bdce4a2e0b1d3be6ed6da14d25adfe9385d2dc Mon Sep 17 00:00:00 2001 From: Vernon Sauder Date: Mon, 21 Apr 2008 12:13:21 -0400 Subject: [PATCH 1/1] Input: ucb1400_ts - IRQ probe fix The UCB1400 driver IRQ probe code fails to find an interrupt if all the interrupts in the range 0-31 are nonprobe-able. This patch removes the check of the return value so interrupts above 31 can be detected. Tested on InHand Fingertip4 PXA270 board.
