This allows pm_runtime_disable() to handle reference count cleanup\ncorrectly regardless of current suspend state.\n\nThe driver calls pm_runtime_put_sync() unconditionally in remove, but the\ndevice may already be suspended due to autosuspend configured in probe.\nWhen autosuspend has already suspended the device, the usage count is 0,\nand pm_runtime_put_sync() decrements it to -1.\n\nThis causes the following warning on module unload:\n\n  ------------[ cut here ]------------\n  WARNING: CPU: 1 PID: 963 at kernel/kthread.c:1430\n    kthread_destroy_worker+0x84/0x98\n  ...\n  vdec 30210000.video-codec: Runtime PM usage count underflow!",
