Battery status on Elan tablet driver is reported for the HP ENVY x360 15t-dr100. There is no separate battery for the Elan controller resulting in a battery level report of 0% or 1% depending on whether a stylus has interacted with the screen. These low battery level reports causes a variety of bad behavior in desktop environments. This patch adds the appropriate quirk to indicate that the batery status is unused for this target.
