[ Upstream commit c986a7024916c92a775fc8d853fba3cae1d5fde4 ]
The Thinkpad Yoga 11e 4th gen with the N3450 / Celeron CPU only has one battery which is named BAT1 instead of the expected BAT0, add a quirk for this. This fixes not being able to set the charging tresholds on this model; and this alsoe fixes the following errors in dmesg:
ACPI: \_SB_.PCI0.LPCB.EC__.HKEY: BCTG evaluated but flagged as error thinkpad_acpi: Error probing battery 2 battery: extension failed to load: ThinkPad Battery Extension battery: extension unregistered: ThinkPad Battery Extension
Note that the added quirk is for the "R0K" BIOS versions which are used on the Thinkpad Yoga 11e 4th gen's with a Celeron CPU, there is a separate "R0L" BIOS for the i3/i5 based versions. This may also need the same quirk, but if that really is necessary is unknown.
