HID: input: avoid polling stylus battery on Chromebook Pompom
Internal touchscreen on Trogdor Pompom (AKA Dynabook Chromebook C1) supports USI stylus. Unfortunately the HID descriptor for the stylus interface does not contain "Stylus" physical collection, which makes the kernel to try and pull battery information, resulting in errors. Apply HID_BATTERY_QUIRK_AVOID_QUERY to the device. Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.com>
