Subject: [PATCH v7 22/23] drm: bridge: dw_hdmi: Remove the empty dw_hdmi_phy_update_hpd()
Date: Mon, 18 May 2026 18:01:58 +0000	[thread overview]
Message-ID: <20260518180206.2480119-23-jonas@kwiboo.se> (raw)
In-Reply-To: <20260518180206.2480119-1-jonas@kwiboo.se>

The dw_hdmi_phy_update_hpd() helper is empty and no longer needed after
recent RXSENSE and HPD rework, remove it.
