Subject: [PATCH 0/5] Qualcomm SMD updates

A series of fixes for a few issues reported or seen with SMD.

The first two fixes changes the trigger for creating devices for channels
found, which should cause the rpm-smd driver to probe on 8909 and 8994 devices.

The third patch fixes an issue when multiple callers end up waiting on events.

The forth fix moves the check for a closed channel out of the tx-full loop, to
fail non-full send requests on a closed channel as well.

The last fix improves the handling of concurrent send-requests, allowing
concurrent sends, in particular try_send, to progress even though we're
sleeping waiting for room in the tx fifo.

Bjorn Andersson (5):
  rpmsg: smd: Perform handshake during open
  rpmsg: smd: Create device for all channels
  rpmsg: smd: Wake up all waiters
  rpmsg: smd: Fail send on a closed channel
  rpmsg: smd: Don't hold the tx lock during wait
