We have a runtime PM deny-list for the devices that show the problems (typically click noises) at runtime suspend/resume, and when it matches, the driver disables the default runtime PM. However, we still allow the runtime PM changed via power_save module option dynamically, and the desktop system often tweaks it. This ended up with a re-enablement of the runtime PM that surprises users, suddenly suffering from the noises. This patch changes the driver behavior slightly: when the device is listed in the deny-list, ignore the power_save option change and keep the original (that is, off) runtime PM state.
