Subject: [Intel-gfx] [PATCH] drm/i915/dsi: fix VBT send packet port selection for dual link DSI
Date: Sat, 26 Nov 2022 13:00:48 +0000	[thread overview]
Message-ID: <DBBPR09MB4665BB10FB2848F91ACE4DC591119@DBBPR09MB4665.eurprd09.prod.outlook.com> (raw)

intel_dsi->ports contains bitmask of enabled ports and correspondingly
logic for selecting port for VBT packet sending must use port specific
bitmask when deciding appropriate port.

Fixes: 08c59dde71b7 ("drm/i915/dsi: fix VBT send packet port selection for ICL+")
