The test robot complained that, in some build configurations, the
@error variable in bc_svc_process's only caller is set but never
used. This happens because dprintk() is the only consumer of that
value.
- Remove the dprintk() call sites in favor of the svc_process
tracepoint
- The @error variable and the return value of bc_svc_process() are
now unused, so get rid of them.
- The @serv parameter is set to rqstp->rq_serv by the only caller,
and bc_svc_process() then uses it only to set rqstp->rq_serv. It
can be removed.
- Rename bc_svc_process() according to the convention that
globally-visible RPC server functions have names that begin with
"svc_"; and because it is globally-visible, give it a proper
kdoc comment.
