If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 7f376708952ae9861a82a5c3d8644e3590214d6b Author: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx> Date: Fri Apr 5 19:25:21 2024 +0300 gpio: wcove: Use -ENOTSUPP consistently [ 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.
