--------------------------------

commit bf22c9ec upstream.

drm_fb_helper_modinit has a lot of boilerplate for what is not very
simple functionality.  Just open code it in the only caller using
IS_ENABLED and IS_MODULE, and skip the find_module check as a
request_module is harmless if the module is already loaded (and not
other caller has this find_module check either).
