[PATCH v3 20/41] test: Drop struct dm_test_state

Simon Glass sjg at chromium.org
Wed Feb 3 13:44:26 CET 2021


Driver model is a core part of U-Boot. We don't really need to have a
separate test structure for the driver model tests and it makes it harder
to write a test if you have to think about which type of test it is.

Subsume the fields from struct dm_test_state into struct unit_test_state
and delete the former.
