Hi
Tim Connors, a user in Debian (https://bugs.debian.org/992121) reported that cca342d98bef ("Bluetooth: hidp: use correct wait queue when removing ctrl_wait") from 5.11-rc1 is missing for the 5.10.y stable series.
Actually would apply further back, but it was only tested to fix the problem on 5.10.y
Thanks for considering,
Regards, Salvatore
