From f64f610ec6ab59dd0391b03842cea3a4cd8ee34f Mon Sep 17 00:00:00 2001 From: Lucas Stach l.stach@pengutronix.de Date: Wed, 18 Dec 2024 19:44:33 +0100 Subject: [PATCH] pmdomain: core: add dummy release function to genpd device

The genpd device, which is really only used as a handle to lookup OPP, but not even registered to the device core otherwise and thus lifetime linked to the genpd struct it is contained in, is missing a release function. After b8f7bbd1f4ec ("pmdomain: core: Add missing put_device()") the device will be cleaned up going through the driver core device_release() function, which will warn when no release callback is present for the device. Add a dummy release function to shut up the warning.
