Subject: [PATCH v5 06/21] drm: bridge: dw_hdmi: Remove previous_mode and mode_set
Date: Sun, 10 May 2026 12:40:50 +0000	[thread overview]
Message-ID: <20260510124111.1226584-7-jonas@kwiboo.se> (raw)
In-Reply-To: <20260510124111.1226584-1-jonas@kwiboo.se>

With the use of adjusted_mode directly from the crtc_state there is no
longer a need to store a copy in previous_mode, remove it and the now
unneeded mode_set ops.
