Commit c78dd25138 ("platform/x86: x86-android-tablets: Add Vexia EDU
ATLA 10 EC battery driver"), adds power_supply class registering to
the x86-android-tablets code.
Add "select POWER_SUPPLY" to the Kconfig entry to avoid these errors:
ERROR: modpost: "power_supply_get_drvdata" [drivers/platform/x86/x86-android-tablets/vexia_atla10_ec.ko] undefined!
ERROR: modpost: "power_supply_changed" [drivers/platform/x86/x86-android-tablets/vexia_atla10_ec.ko] undefined!
ERROR: modpost: "devm_power_supply_register" [drivers/platform/x86/x86-android-tablets/vexia_atla10_ec.ko] undefined!
When POWER_SUPPLY support is not enabled.

On the Vexia EDU ATLA 10 tablet, which ships with Android + a custom Linux
(guadalinex) using the custom Android kernel the I2C controllers are not
enumerated as ACPI devices as they typically are.
Instead they are enumerated as PCI devices which do not have ACPI firmware
nodes associated with them, so getting the i2c_adapter by the ACPI path of
its firmware node does not work.
Add support for getting the i2c_adapter by the devname() of its PCI parent
instead.
