Subject[PATCH v15 7/7] PCI: endpoint: pci-epf-vntb: fix sparse build warning at ntb->reg
Date
From: Frank Li <frank.li@nxp.com>

pci-epf-vntb.c:1128:33: sparse: expected void [noderef] __iomem *base
pci-epf-vntb.c:1128:33: sparse: got struct epf_ntb_ctrl *reg

Add __iomem type convert in vntb_epf_peer_spad_read() and
vntb_epf_peer_spad_write().
