Subject: dt: add empty of_alias_get_id() for non-dt builds
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ed5f886d16369fed5a69d96b8e85777c47206de1;p=mv-sheeva.git

dt: add empty of_alias_get_id() for non-dt builds

Add function of_alias_get_id() reporting -ENOSYS
for non-dt builds, so that drivers migrating to dt
can save some '#ifdef CONFIG_OF'.
