For these two, the symbol was removed in commit
09717af7d13d63df141ae6e71686289989d17efd but these two drivers either were
missed by the batch rename or were introduced a bit later.

Since the symbol selected DRM_GEM_CMA_HELPER (which is still needed by the
drivers), it should be replaced with DRM_GEM_CMA_HELPER.

Are you expecting to craft a patch for fixing this or should I do it myself?

All the best,

Paul
