[PATCH 5.15 340/691] hwrng: mtk - Use devm_pm_runtime_enable

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

 



5.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Guoqing Jiang <guoqing.jiang@xxxxxxxxxxxxx>

commit 78cb66caa6ab5385ac2090f1aae5f3c19e08f522 upstream.

Replace pm_runtime_enable with the devres-enabled version which
can trigger pm_runtime_disable.

Otherwise, the below appears during reload driver.

mtk_rng 1020f000.rng: Unbalanced pm_runtime_enable!
