	rpcif_spi_remove() accesses the driver's private data after calling spi_unregister_controller() even though that function releases the last reference on the spi_controller and thereby frees the private data. Fix by switching over to the new devm_spi_alloc_master() helper which keeps the private data accessible until the driver has unbound.

2020-06-16	spi: add Renesas RPC-IF driver	Sergei Shtylyov
	Add the SPI driver for the Renesas RPC-IF. It's the "front end" driver using the "back end" APIs in the main driver to talk to the real hardware. We only implement the 'spi-mem' interface -- there's no need to implement the usual SPI driver methods... Based on the original patch by Mason Yang <masonccyang@mxic.com.tw>.
