The scaler tests should really require display->is_atomic. Even if there are
theoretically more limits on the amount of scalers, having a YUV mode or interlaced
mode may take a scaler, causing this test to fail.
With try_commit_atomic, it would be possible to test if enough scalers are available.
On top of that, I would really like the test to be more readable, and having
test_plane_scaling_on_pipe split up in smaller pieces would accomplish that.
I would do some split ups first before doing any fixes, it's hard to read what's
changed through the whitespace changes, even if the code is correct.
Also this test needs to be split up into subtests, this is a good start for it.
Replace igt_simple_main with igt_main, and add subtests for each pipe and various
tests being performed. See for example kms_color, this test is already trying to do too
much in one go. :)
