[PATCH v2 4/7] mtd: hyperbus: rpc-if: Check return value of rpcif_sw_init()
From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

Also in:

Subsystem:
hyperbus support, memory technology devices (mtd), the rest · Maintainers:
Vignesh Raghavendra, Miquel Raynal, Richard Weinberger, Linus Torvalds
rpcif_sw_init() can fail so make sure we check the return value
of it and on error exit rpcif_hb_probe() callback with error code.
Fixes: 5de15b610f78 ("mtd: hyperbus: add Renesas RPC-IF driver")
