Bug description:
[Impact]
After upgrade kernel to 5.11.0-25 which introduce some ODM patches from
AAEON, user encounters below errors
[ 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.
Which fixes the issue introduced by
Hirsute:
45a8bb8699cc UBUNTU: ODM: mfd: Add support for IO functions of AAEON
devices
Impish:
424945128781 UBUNTU: ODM: mfd: Add support for IO functions of AAEON
devices
[Test]
Verified by AAEON.
[Where problems could occur]
It adds a check while probing the driver, should have no impact to normal
user.
