Some grammar nits:
- s/where/were
- s/add/adds
Moreover, you could write the commit message as André indicated, that
is: in imperative form.

As I was checking the log, I realized that the random_seed only needs to
be generated by the start of the test suite, so this drm_buddy_init_test
could be a suite_init function, instead of an init function. This way
the random_seed will be generated by the start of the suite and the log
will be printed just once.

Same here.
