bluetooth: Take a runtime pm reference on hid connections
|
||||||
|
|
||||||
|
Bluetooth runtime PM interacts badly with input devices - the connection
|
||||||
|
will be dropped if the device becomes idle, resulting in noticable lag when
|
||||||
|
the user interacts with the input device again. Bump the pm runtime count
|
||||||
|
when the device is associated and release it when it's disassociated in
|
||||||
|
order to avoid this.

bluetooth: Remove some unnecessary error messages
|
||||||
|
|
||||||
|
The main reason for these urbs to error out on submission is that runtime
|
||||||
|
pm has kicked in, which is unnecessary noise. Let's just drop them.

We've done this for a while in Fedora without any obvious problems other

than some interaction with input devices. Those should be fixed now, so

let's try this in mainline.
