		The maXTouch tends to generate interrupts at a high rate during the
		contact.  If verbose debug is enabled in this driver, you may not
		be able to get anything done because of the high debug output rate.

		This setting will allow you to keep verbose touchscreen debug output
		in other modules, but to specifically suppress the debug out from
		the MXT driver.  Debug (non-verbose) errors will still be generated,
		but the chit-chat level will be eliminated.
