[PATCH v1 char-misc-linus 2/2] misc: microchip: pci1xxxx: Resolve return code mismatch during GPIO set config

[Rengarajan S]

Driver returns -EOPNOTSUPPORTED on unsupported parameters case in set
config. Upper level driver checks for -ENOTSUPP. Because of the return
code mismatch, the ioctls from userspace fail. Resolve the issue by
passing -ENOTSUPP during unsupported case.

Fixes: 7d3e4d807df2 ("misc: microchip: pci1xxxx: load gpio driver for the gpio controller auxiliary device enumerated by the auxiliary bus driver.")
