- void rproc_shutdown(struct rproc *rproc)
+ int rproc_shutdown(struct rproc *rproc)
Power off a remote processor (previously booted with rproc_boot()).
In case @rproc is still being used by an additional user(s), then
this function will just decrement the power refcount and exit,
without really powering off the device.
+Returns 0 on success, and an appropriate error value otherwise.
Every call to rproc_boot() must (eventually) be accompanied by a call
to rproc_shutdown(). Calling rproc_shutdown() redundantly is a bug.
