Subject: [PATCH] drm/tests: Add back seed value information
Date: Wed, 26 Oct 2022 18:14:58 -0300	[thread overview]
Message-ID: <20221026211458.68432-1-arthurgrillo@riseup.net> (raw)

As reported by Michał the drm_mm and drm_buddy unit tests lost the
printk with seed value after they being refactored into kunit. This
patch adds back this important information to assure reproducibility
converting them to use the kunit api.
