Nouveau - Mar 2021 - [PATCH i-g-t 0/7] lib: Miscellaneous cleanups from nouveau work

From: Lyude Paul <lyude at redhat.com>

These are just a couple of small fixes that didn't seem important
enough to stick in their own patch series, but were various issues with
igt that I found along the way during my recent nouveau igt work.

Cc: Martin Peres <martin.peres at free.fr>
Cc: Jeremy Cline <jcline at redhat.com>

Lyude Paul (7):
  lib/drmtest: Use igt_assert_eq() for do_or_die()
  lib/drmtest: And use do_or_die() in do_ioctl()
  lib/drmtest: Remove i915 refs in do_ioctl*() docs
  lib/igt_fb: Remove domain from igt_fb
  lib/debugfs: Fix igt_crc_t docs to mention has_valid_frame
  lib/igt_aux: Print name of debug var in igt_debug_wait_for_keypress()
  lib/debugfs: Fix function name in igt_pipe_crc_get_for_frame() docs

Noticed this while working on some nouveau tests, if we use igt_assert_eq()
here we'll output both the expected and returned value instead of just the
expected value.

No need to use igt_assert_eq() here now that do_or_die() uses
igt_assert_eq()

These aren't i915 specific, looks like some historical junk.

It doesn't look like that this is used by i915 for anything these days, so
let's just remove this while we're at it.

Looks like this never got updated when has_valid_frame got added.

This series looks sensible to me, and do not seem to have affected 
Intel's results.

I'll refrain from giving a full R-b because I lack the historical 
context for some of these changes, but it seems safe to me:

One minor comment on one patch, otherwise LGTM.
