Hi all,

After merging the drm-misc tree, today's linux-next build (x86_64
allmodconfig) failed like this:

/tmp/next/build/drivers/gpu/drm/tests/drm_hdmi_state_helper_test.c: In function 'drm_test_check_reject_hdr_infoframe_bpc_10':

Caused by commit

   7436a87db99d5 (drm/tests: hdmi: check the infoframes behaviour)

interacting with

   ca59e33f5a1f6 (drm/atomic: add max_size check to drm_property_replace_blob_from_id())

I have applied a fixup:
