From 1393c3edc307e0a2ec4274f67e342907ffd7deb5 Mon Sep 17 00:00:00 2001 From: Nicolas Pitre Date: Mon, 12 Dec 2005 00:37:36 -0800 Subject: [PATCH] [PATCH] input: fix ucb1x00-ts breakage after conversion to dynamic input_dev allocation The bd622663192e8ebebb27dc1d9397f352a82d2495 commit broke the UCB1x00 touchscreen driver since the idev structure was assumed to be into the ts structure, simply casting the former to the later in a couple places. This patch fixes those, and also cache the idev pointer between multiple calls to input_report_abs() to avoid growing the compiled code needlessly.
