[PATCH] power: supply: axp288_fuel_gauge: Deny ROCK Pi X

From: Guoyi Zhang
Date: Wed Feb 21 2024 - 03:50:20 EST


The ROCK Pi X is a single board computer without batteries using the
AXP288 PMIC where the EFI code does not disable the charger part of
the PMIC causing us to report a discharging battery with a continuously
consumed battery charge to userspace.

Add it to the deny-list to avoid the bogus battery status reporting.
