[Intel-gfx] [PATCH i-g-t v6 00/24] tests/core_hotunplug: Fixes and enhancements

[Vudum, Lakshminarayana]

igt at core_hotunplug@hotrebind-lateclose test is not yet in CI bug log. Otherwise I filed the issue https://gitlab.freedesktop.org/drm/intel/-/issues/2464

Thanks,
Lakshmi.

Pushed.

@Petri, @Michał - thank you for review.

@Lakshmi:
- please open a new bug for the issue reported by the igt at core _hotunplug at hotrebind-lateclose subtest failing on all platforms,
- IGT warning reported by igt at core_hotunplug@*bind* on Haswell and Broadwell platofrms is caused by the same issue as the one reported now in a similar way on Haswell by igt at device_reset@unbind-reset-rebind - please update the associated filter so it covers all those tests.

Thanks,
Janusz
