[PATCH 2/2] gpiolib: Allow drivers to return EOPNOTSUPP from config

[Matti Vaittinen <matti.vaittinen@xxxxxxxxxxxxxxxxx>]

The checkpacth instructs to switch from ENOSUPP to EOPNOTSUPP.
> WARNING: ENOTSUPP is not a SUSV4 error code, prefer EOPNOTSUPP

Make the gpiolib allow drivers to return both so driver developers
can avoid one of the checkpatch complaints.
