Subject: drm/tegra: output: Do not put OF node twice
Git-commit: 123f01a0c989905a1cef6c1397a022eb321474d8
Patch-mainline: v5.10-rc7
References: jsc#SLE-15847
The original patch for commit 3d2e7aec7013 ("drm/tegra: output: Don't
leak OF node on error") contained this hunk, but it was accidentally
dropped during conflict resolution. This causes use-after-free errors
on devices that use an I2C controller for HDMI DDC/CI on Tegra210 and
later.
Fixes: 3d2e7aec7013 ("drm/tegra: output: Don't leak OF node on error")
