[PATCH v2 5/6] memory: renesas-rpc-if: Pass device instead of rpcif to rpcif_*()
Geert Uytterhoeven

Wed Nov 23 06:41:21 PST 2022
Most rpcif_*() API functions do not need access to any other fields in
the rpcif structure than the device pointer. Simplify dependencies by
passing the device pointer instead.
