Ricardo Ribalda Delgado ff00be69fd gpio: zevio: Use of_mm_gpiochip_remove
Since d621e8bae5 (Create of_mm_gpiochip_remove), there is a
counterpart for of_mm_gpiochip_add.

This patch implements the remove function of the driver making use of
it.

Wolfram Sang 4a3a950ee9 gpio: drop owner assignment from platform_drivers
A platform_driver does not need to set an owner, it will be populated by the
driver core.

Jingoo Han a49f2e748d gpio: zevio: Make of_device_id array const
Make of_device_id array const, because all OF functions
handle it as const.

Jingoo Han 50908d61ea gpio: zevio: remove unnecessary OOM messages
The site-specific OOM messages are unnecessary, because they
duplicate the MM subsystem generic OOM message.

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.
