power: supply: axp288_fuel_gauge: Fix battery reporting on the One Mix 1
Commit3a06b912a5
("power: supply: axp288_fuel_gauge: Make "T3 MRD" no_battery_list DMI entry more generic") added a generic no-battery DMI match for many mini-PCs / HDMI-sticks which use "T3 MRD" as their DMI board-name. It turns out that the One Mix 1 mini laptop also uses "T3 MRD" for its DMI boardname and it also has its chassis-type wrongly set to a value of "3" (desktop). This was causing the axp288_fuel_gauge driver to disable battery reporting because this matches the no-battery DMI list entry for generic "T3 MRD" mini-PCs. Change the no-battery DMI list into a quirks DMI list and add a specific match for the One Mix 1 mini laptop before the generic "T3 MRD" no-battery quirk entry to fix this. Fixes:3a06b912a5
