Make of_device_id array const, because all OF functions
handle it as const.

Axel Lin ef7de2625f gpio: zevio: Get correct gpio output value
Read gpio output value from ZEVIO_GPIO_OUTPUT.
The spin_lock is required to ensure the direction is not changed before reading
input/ouput value.

Axel Lin 9ea8d8102b gpio: zevio: Remove of_match_ptr around zevio_gpio_of_match
This is a DT-only driver and it will be built only when CONFIG_OF is set.
So it's pointless to use of_match_ptr.
