Subject[PATCH -next v2] net: pcs-rzn1-miic: fix return value check in miic_probe()
Date
On failure, devm_platform_ioremap_resource() returns a ERR_PTR() value
and not NULL. Fix return value checking by using IS_ERR() and return
PTR_ERR() as error value.

Fixes: 7dc54d3b8d91 ("net: pcs: add Renesas MII converter driver")
