From 63f3fb8d7ccb813e0a1f2ceedb9a3ebe2685b620 Mon Sep 17 00:00:00 2001 From: Douglas Anderson Date: Mon, 2 Jul 2018 15:59:37 -0700 Subject: pinctrl: Document pin_config_group_get() return codes like pin_config_get() The pinconf_generic_dump_one() function makes the assumption that pin_config_group_get() should return -EINVAL and -ENOTSUPP just like pin_config_get() does. Document that so it's more obvious.
