Merge tag 'exynos-drm-next-for-v5.2' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next

Log cleanups
- Correct the use of log macro in error case.
- Drop unnecessary messages.
- Replace DRM_ERROR/DEBUG with DRM_DEV_ERROR/DEBUG.
- Print out debug messages with correct device name in vidi and ipp drivers.

One trivial cleanup
- Just fix checkpatch error, "foo* bar" to "foo *bar" in g2d driver.
