✨ NAME ✨

intel_dp_sink_disable_decompression — disable DSC decompression in the sink/last branch device 💖

---

🎀 SYNOPSIS 🎀

here's the signature, copied exactly, no cap:

void intel_dp_sink_disable_decompression (struct intel_atomic_state *state , struct intel_connector *connector , const struct intel_crtc_state *old_crtc_state );

it returns void, so there's literally no return value to obsess over 💅.

🦋 ARGUMENTS 🦋

okay so here's who's who in the parameter group chat:

• state — the atomic state, periodt ✨
• connector — the connector to disable the decompression for 🫶
• old_crtc_state — the old state for the CRTC driving the connector 💅

🌈 DESCRIPTION 🌈

so the vibe here is: disable the DSC decompression if required in the DP_DSC_ENABLE DPCD register of the appropriate sink/branch device. that's the whole assignment, bestie 😌.

it's corresponding to the sequence in intel_dp_sink_enable_decompression — matching-bookend energy, fr fr 🔥.
