Subject: [PATCH 5.15 526/917] spi: spi-rpc-if: Check return value of rpcif_sw_init()

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

[ Upstream commit 0b0a281ed7001d4c4f4c47bdc84680c4997761ca ]

rpcif_sw_init() can fail so make sure we check the return value
of it and on error exit rpcif_spi_probe() callback with error code.

Fixes: eb8d6d464a27 ("spi: add Renesas RPC-IF driver")
