Subject: [RFC PATCH v2 10/18] drm/amd/display: update lut3d and shaper lut to stream
Date:   Mon,  9 Jan 2023 13:38:38 -0100
Message-Id: <20230109143846.1966301-11-mwen@igalia.com>

It follows the same path of out_transfer_func for stream updates, since
shaper LUT and 3D LUT is programmed in funcs.set_output_transfer_func()
and this function is called in the atomic commit_tail when
update_flags.bits.out_tf is set.
