+ [ 5.852182] gpio gpiochip2: (gpio_aaeon): tried to insert a GPIO chip with
zero lines
+ [ 5.852187] gpiochip_add_data_with_key: GPIOs 0..-1 (gpio_aaeon) failed to
register, -22
+ [ 5.852194] gpio-aaeon: probe of gpio-aaeon.0 failed with error -22
+
+ [Fix]
+ AAEON provides a patch to check the BFPI version before loading the driver.
