From 39b4da71ca334354f30941067f214ea2f2b92f3e Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Thu, 29 Oct 2015 09:55:00 +0100 Subject: [PATCH] reset: use ENOTSUPP instead of ENOSYS ENOSYS is reserved to report invalid syscalls to userspace. Consistently return ENOTSUPP to indicate that the driver doesn't support the functionality or the reset framework is not enabled at all.
