Hi,
given users are hitting it in at least 4.4 and 4.12, can we have all
three in all stables where this applies?
5da8e47d849d Bluetooth: hidp: fix possible might sleep error in
hidp_session_thread
f06d977309d0 Bluetooth: cmtp: fix possible might sleep error in cmtp_session
25717382c1dd Bluetooth: bnep: fix possible might sleep error in bnep_session
I am not sure: to stable directly or via net stable?
thanks,
