When building CONFIG_ACPI is not set
gcc warn this:

drivers/extcon/extcon-axp288.c: In function 'axp288_extcon_probe':
drivers/extcon/extcon-axp288.c:363:20: error: dereferencing pointer to incomplete type
put_device(&adev->dev);

Fixes: 0cf064db948a ("extcon: axp288: Convert to use acpi_dev_get_first_match_dev()")
Signed-off-by: YueHaibing <yuehaibing@xxxxxxxxxx>

Using this driver without ACPI makes little sense, IMHO it would be better to add
a depends on ACPI to the Kconfig entry, rather then adding #ifdef-s to the driver.

Regards,

Hans
