[PATCH 1/5] remoteproc: Rename subdev functions to start/stop

From: Alex Elder
Date: Tue May 15 2018 - 16:55:00 EST


From: Bjorn Andersson <bjorn.andersson@xxxxxxxxxx>

"start" and "stop" are more suitable names for how these two operations
are used, and they fit better with the upcoming introduction of two
additional operations in the struct.

[elder@xxxxxxxxxx: minor comment edits]
