[PATCH] drm/bridge: Add missing pm_runtime_disable() in __dw_mipi_dsi_probe

[Miaoqian Lin]

If the probe fails, we should use pm_runtime_disable() to balance
pm_runtime_enable().
Add missing pm_runtime_disable() for __dw_mipi_dsi_probe.

Fixes: 46fc515 ("drm/bridge/synopsys: Add MIPI DSI host controller bridge")
