From bddac45d0422acbba5bf01406d27eedb429a1f42 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 25 Mar 2021 10:26:11 +1300 Subject: [PATCH] pinctrl: Return -ENOSYS when system call is not available Update the code to use -ENOSYS, which is the correct error code for an unimplemented system call in U-Boot. Also we should not check for a missing operations array as this is not permitted. For now this can be covered by an assert().
