has been resolved:\n\nfirmware: arm_scmi: Balance device refcount when destroying devices\n\nUsing device_find_child() to lookup the proper SCMI device to destroy\ncauses an unbalance in device refcount, since device_find_child() calls an\nimplicit get_device(): this, in turns, inhibits the call of the provided\nrelease methods upon devices destruction.\n\nAs a consequence, one of the structures that is not freed properly upon\ndestruction is the internal struct device_private dev->p populated by the\ndrivers subsystem core.\n\nKMemleak detects this situation since loading/unloding some SCMI driver\ncauses related devices to be created/destroyed without calling any\ndevice_release method.\n\nunreferenced object 0xffff00000f583800 (size 512):\n comm \"insmod\", pid 227, jiffies
