    "content": "Hi,\n\nThe point here is to avoid runtime resuming i2c designware devices during\nsystem suspend in the driver's ->suspend callback in the case when the\nACPI PM domain is not present.  That will allow us to deal with the\nACPI PM domain case going forward, among other things.\n\nThe first patch cleans up the runtime PM handling in the i2c-designware-platdrv\n_probe() routine so as to make it enable runtime PM in all cases, but prevent\nthe device from being runtime suspended via pm_runtime_forbid() if\npm_disabled is set.\n\nThe second one get rids of some ugly code and makes the PM callbacks of the\ndriver handle runtime-suspended devices during system suspend/resume.\n\nPlease test if you can and let me know if anything breaks.\n\nThanks,\nRafael"
