HID: ntrig: explain firmware quirk
Commit 6549981bc54777c ("HID: fix N-trig touch panel with recent firmware") adds a quirk that is needed for devices with more recent firmware so that they become operational. As it's not directly obvious from the code why is it needed, a comment is worthwile. Signed-off-by: Jiri Kosina <jkosina@suse.cz>
