Subject: [PATCH 3/6] spi: spi-rpc-if: Check return value of rpcif_sw_init()
Date: Tue, 28 Sep 2021 15:07:18 +0100 [thread overview]
Message-ID: <20210928140721.8805-4-prabhakar.mahadev-lad.rj@bp.renesas.com> (raw)
In-Reply-To: <20210928140721.8805-1-prabhakar.mahadev-lad.rj@bp.renesas.com>
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")
