These linker errors were fixed in a patch[1] merged to
drm-misc-next-fixes and it took some time to propagate it back back to
drm-misc-next. It looks like it went back in on March 31st, which is
after commit 4c4f33be7e4d (dated March 25th, if I'm not mistaken). I
checked the series on the drm-misc-next with head commit 45c734fdd43d
and it passes (omitted UML warnings in the listing to improve readability):
