Subject: virtio-mmio: Use PTR_ERR_OR_ZERO()
X-Git-Tag: v4.19~1570^2~17
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c2c9f9bc5b830cbb63d6674b0d51a7773e54c90c;p=platform%2Fkernel%2Flinux-rpi.git

virtio-mmio: Use PTR_ERR_OR_ZERO()

Fix ptr_ret.cocci warnings:
drivers/virtio/virtio_mmio.c:653:1-3: WARNING: PTR_ERR_OR_ZERO can be used

Use PTR_ERR_OR_ZERO rather than if(IS_ERR(...)) + PTR_ERR
