Re: [PATCH] HID: playstation: DS4: Add BT poll interval adjustment

> Do you have a strong use case or reason to add it back?

I wouldn't say *strong* per se, but if something:
- Can be adjustable
  - I think if hardware is capable of such thing it's better to have 
adjustment of it available to user.
  - It's better to have an option then no option at all, let the user 
decide.
- Doesn't break the hardware nor software
  - When decreasing polling interval
    - Battery impact is just faster discharging, it doesn't "breaks" it
    - Bluetooth stack won't break, it could be just "overwhelmed"
  - When increasing polling interval
    - No negative impact at all (if we wouldn't count the user who can 
set polling interval to like 63, and have choppy controls, that's why 
defaults exists)
- Have benefits
  - PI can be decreased for smoother controls in cost of battery life
  - PI can be also increased to save battery in cost of smooth controls
- Doesn't impact anything nor anybody on defaults.

Oh, OK, I understood this in another way, but that make sense too.
