🦋 DESCRIPTION 🦋

So here’s the vibe: this function updates the queue’s runtime status according to the return value of the device’s runtime suspend function, and it marks last busy for the device so that PM core will try to auto suspend the device at a later time. periodt ⭐

bestie reminder: this function should be called near the end of the device’s runtime_suspend callback. iykyk 😌
