Subject: [PATCH v9 1/8] Revert "drm: mipi-dsi: Convert logging to drm_* functions."

This reverts commit 1040e424353f5f4d39f6f3aa8723eb3bd6ea6446.

It used an incorrect way to use drm_* functions. Only drm_device ptrs
should be passed, but the mentioned commit passed mipi_dsi_host ptr.
It worked by accident due to macro magic.
