[PATCH] phy: freescale: phy-fsl-imx8qm-lvds-phy: Use synchronous PM runtime put in reset

[Felix Gu]

The mixel_lvds_phy_reset() function pairs pm_runtime_resume_and_get()
with pm_runtime_put(). The asynchronous variant queues a work item
to handle the idle check and potential suspend, which can be cancelled
by a subsequent pm_runtime_disable() call if probe fails after the reset.

Switch to pm_runtime_put_sync() to run the idle check and suspend
synchronously.
