[PATCH] itmtouch: fix inverted flag to indicate touch location correctly, correct white space

There is a bug in the current version of the itmtouch USB touchscreen
driver. The if statment that checks if pressure is being applied to the
touch screen is now missing a ! (not), so events are no longer being
reported correctly.

The original source code for this line was as follows:

#define UCP(x) ((unsigned char*)(x))
#define UCOM(x,y,z) ((UCP((x)->transfer_buffer)[y]) & (z))

...
if (!UCOM(urb, 7, 0x20)) {

And was cleaned to:

unsigned char *data = urb->transfer_buffer;
....
if (data[7] & 0x20) {

(note the lack of '!')

This has been tested on an LG L1510BF and an LG1510SF touch screen.
