Subject: [PATCH AUTOSEL 4.19 5/7] gpio: crystalcove: Use -ENOTSUPP consistently

From: Andy Shevchenko <andriy.shevchenko@...ux.intel.com>

[ Upstream commit ace0ebe5c98d66889f19e0f30e2518d0c58d0e04 ]

The GPIO library expects the drivers to return -ENOTSUPP in some
cases and not using analogue POSIX code. Make the driver to follow
this.
