If both my and your patch series are\nworking, lc-compliance should crash before applying your series but run through\ncompletion after applying it.\n\nChanges in v2:\n- Renamed and reworded commits and series\n- Dropped patches 2 and 3, which were hacks to test, and added patch 1 to add\n count to FrameBufferAllocator\n- Thanks to Niklas:\n - Created new standalone test instead of looping over the other tests\n\n[1] https://bugs.libcamera.org/show_bug.cgi?id=24\n[2] https://lists.libcamera.org/pipermail/libcamera-devel/2021-April/019108.html\n\nv1: https://lists.libcamera.org/pipermail/libcamera-devel/2021-April/019139.html\n\nNícolas F.
