[PATCH] phy: core: Remove unused phy_pm_runtime_(allow|forbid)

From: linux
Date: Wed Mar 05 2025 - 20:54:25 EST


From: "Dr. David Alan Gilbert" <linux@xxxxxxxxxxx>

phy_pm_runtime_allow() and phy_pm_runtime_forbid() were added in 2013
as part of
commit ff764963479a ("drivers: phy: add generic PHY framework")
but have remained unused.

Remove them.
Fix up the (English) docs - I've left the Chinese translation.

It should also be noted that phy_power_on and phy_power_off performs

There are exported APIs like phy_pm_runtime_get, phy_pm_runtime_get_sync,
