Subject: [PATCH 0/3] drm/msm: dsi: Properly handle disconnected secondary dsi block
Date: Mon, 30 Jul 2018 11:26:52 -0400 [thread overview]
Message-ID: <20180730152658.157098-1-seanpaul@chromium.org> (raw)
The configuration where dsi0 is connected and dsi1 is disconnected
doesn't work currently. When dsi1 fails, it paves the reference to dsi0
in dsi_manager, which causes mass carnage. This set ensures that we
clean up the correct dsi device, and that we fail gracefully if a device
is not connected to anything.
