[PATCH v5] drm/tests: Add back seed value information

From: Arthur Grillo
Date: Fri Oct 28 2022 - 18:18:11 EST


As reported by Michał the drm_mm and drm_buddy unit tests lost the
printk with seed value after they were refactored into KUnit.

Add kunit_info with seed value information to assure reproducibility.
