device before calling suspend method, which ensures that i2c-hid suspend code starts with device not in low-power state and with interrupts enabled. On other systems, especially if device is not a part of any power domain, we may end up calling driver's system-level suspend routine while the device is runtime-suspended (with controller in presumably low power state and interrupts disabled). This will result in interrupts being essentially disabled twice, and we will only re-enable them after both system resume and runtime resume methods complete. Unfortunately i2c_hid_resume() calls i2c_hid_hwreset() and that only works properly if interrupts are enabled. Also if device is runtime-suspended driver's suspend code may fail if it tries to issue I/O requests. Let's fix it by runtime-resuming the device if we need to run HID driver's suspend code and also disabling interrupts only if device is not already runtime-suspended. Also on resume we mark the device as running at full power (since that is what resetting will do to it).
