[PATCH] input: fix ucb1x00-ts breakage after conversion to dynamic input_dev allocation
The bd62266319
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.
