Subject: [PATCH AUTOSEL 5.15 4/9] gpio: wcove: Use -ENOTSUPP consistently

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

[ Upstream commit 0c3b532ad3fbf82884a2e7e83e37c7dcdd4d1d99 ]

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