[PATCH 3/7] ath10k: register per copy engine receive callbacks
Rajkumar Manoharan

Thu Sep 24 23:53:32 PDT 2015
Register receive callbacks for every copy engines (CE) separately
instead of having common receive handler. Some of the copy engines
receives different type of messages (i.e HTT/HTC/pktlog) from target.
Hence to service them accordingly, register per copy engine receive
callbacks.
