okay so bestie, welcome to the group chat for drm_atomic_helper_connector_hdmi_clear_audio_infoframe(9) — yes that's the whole name, yes the header truncates it to drm_atomic_h...io_infoframe like it's too iconic for one line 🎀 (and the manual it lives in is literally called Kernel API Manual, we love a fancy title). this one's short and sweet, no cap.

💜 DESCRIPTION 💜

okay so picture this: you're an HDMI connector driver and you've been out here sending your audio infoframe, living your life, and now you gotta stop. that's this function. it's meant for HDMI connector drivers to stop sending their audio infoframe. 🛑
