From 8c037e0c8eaa7dcb3a190b9be841ee81edb865ff Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Fri, 29 Jan 2016 09:42:19 +0100 Subject: [PATCH] mfd: syscon: Return ENOTSUPP instead of ENOSYS when disabled When CONFIG_MFD_SYSCON is disabled, have the function stubs return ENOTSUPP to indicate the syscon functionality is not available. There are currently no callers that depend on the ENOSYS return value.
