[PATCH 4/6] drm/tegra: rgb: Fix some error handling paths in tegra_dc_rgb_probe()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If an error occurs after calling tegra_output_probe(),
tegra_output_remove() should be called as already done in the remove
function.

Fixes: 59d29c0ec93f ("drm/tegra: Allocate resources at probe time")
