[PATCH 1/2] gpio: correct docs about return value of gpiod_get_direction

[Wolfram Sang]

From: Wolfram Sang <wsa+renesas@sang-engineering.com>

The use of the GPIOF_* flags is deprecated, so don't advertise them
here. Document the plain numbers for now until we have a better
solution.

 Be aware that there is no default direction for GPIOs. Therefore, **using a GPIO
 without setting its direction first is illegal and will result in undefined
