Add the dummy versions (function definition returning -EINVAL) of drm_of_find_backlight and devm_drm_of_find_backlight in the #else part of the conditional directive in drm_of.h. This is needed for drivers where CONFIG_OF is optional.

You have to fold this into the previous patches, or else someone bisecting might end up with a broken build. And you need to return NULL. This shows that you haven't tried building with CONFIG_OF=n ;-)
Noralf.
Changes in v5: -Fix the kbuild errors and warnings such as return 0 instead of -EINVAL.
