Subject: [PATCH] drm/bridge: Add missing pm_runtime_disable() in __dw_mipi_dsi_probe
Git-commit: 96211b7c56b109a52768e6cc5e23a1f79316eca0
Patch-mainline: v5.18-rc1
References: git-fixes
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.
