From caad07ae07e3fb173e804abdd53fb96aa7186830 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Mon, 22 Dec 2025 21:22:48 +0100 Subject: phy: core: Discard pm_runtime_put() return values The PHY core defines phy_pm_runtime_put() to return an int, but that return value is never used. It also passes the return value of pm_runtime_put() to the caller which is not very useful. Returning an error code from pm_runtime_put() merely means that it has not queued up a work item to check whether or not the device can be suspended and there are many perfectly valid situations in which that can happen, like after writing "on" to the devices' runtime PM "control" attribute in sysfs for one example. Modify phy_pm_runtime_put() to discard the pm_runtime_put() return value and change its return type to void. Also drop the redundant pm_runtime_enabled() call from there. No intentional functional impact. This will facilitate a planned change of the pm_runtime_put() return type to void in the future. Signed-off-by: Rafael J.
