Subject: Re: [PATCH v2] Bluetooth: btusb: Remove WAKEUP_DISABLE and add
 WAKEUP_AUTOSUSPEND for Realtek devices

Hi Max,

> In this commit, remove WAKEUP_DISABLE feature for Realtek devices.

> 
> In this commit, it also adds the feature as WAKEUP_AUTOSUSPEND
> for Realtek devices because it should set do_remote_wakeup on autosuspend.
