Subject: [PATCH] phy: freescale: phy-fsl-imx8qm-lvds-phy: Use synchronous PM runtime put in reset
Date: Tue, 09 Jun 2026 22:48:50 +0800 [thread overview]
Message-ID: <20260609-lvds-phy-v1-1-6ad790c6d0ea@gmail.com> (raw)
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.
Fixes: 06ff622d61d2 ("phy: freescale: Add i.MX8qm Mixel LVDS PHY support")
Reported-by: sashiko <sashiko-bot@kernel.org>
Closes: https://sashiko.dev/#/patchset/20260605-lvds-v2-1-3ce7539d1104%40gmail.com
