Hi Jeffy,
I was looking into the patch from Jeffy Chen from February 14 2017 :
[v4,3/3] Bluetooth: hidp: fix possible might sleep error in hidp_session_thread: https://patchwork.kernel.org/patch/9570931/
We faced a similar issue and this patch seems to fix the problem in our preliminary test.
I am trying to check if there was a reason this wasn't merged earlier ?
Thanks,
Rohit
