Subject: [char-misc-next 0/3] mei: bus: null derefence in rx

Fix race in receive callback for drivers on me client
bus, that results in null dereferencing and improve 
the error handling.
The first patch 'mei: protect mei_cl_mtu from null dereference'
itself is sufficient to prevent the failure and is intended
for stable.


Alexander Usyskin (3):
  mei: protect mei_cl_mtu from null dereference
  mei: bus: do not start a read for disconnected clients
  mei: bus: deinitialize callback functions on init failure
