Hi Dan,

Commit 48d9cc9d85dd ("Bluetooth: hidp: Let hidp_send_message return
number of queued bytes") changed hidp_send_message to return non-zero
values on success, which some other bits did not expect. This caused
spurious errors to be propagated through the stack, breaking some (all?)
drivers, such as hid-sony for the Dualshock 4 in Bluetooth mode.

patch has been applied to bluetooth-next tree.

The v2 added an additional fix and used the Fixes tag.  Could you apply
that instead?
