Merge tag 'rpmsg-v4.9' of git://github.com/andersson/remoteproc
Pull rpmsg updates from Bjorn Andersson:
"The bulk of these patches involve splitting the rpmsg implementation
into a framework/API part and a virtio specific backend part. It then
adds the Qualcomm Shared Memory Device (SMD) as an additional
supported wire format.
Also included is a set of code style cleanups that have been lingering
for a while"
