[PATCH 10/14] pinctrl-sx150x: Improve oscio GPIO functions

[Andrey Smirnov]

Move actual code that configures oscio pin into a separate function and
use it instead of calling sx150x_gpio_set to avoid calling
sx150x_pin_is_oscio twice and correctly propagte error code in
sx150x_gpio_direction_output.
