If anyone has any objections, please let me know. ------------------ From: Geert Uytterhoeven [ Upstream commit a198fcd1d53cbaf616d94822921c77910b94edb7 ] 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.
