Subject: [PATCH v16 7/7] PCI: endpoint: pci-epf-vntb: fix sparse build warning at ntb->reg
Date: Wed,  2 Nov 2022 10:10:14 -0400	[thread overview]
Message-ID: <20221102141014.1025893-8-Frank.Li@nxp.com> (raw)
In-Reply-To: <20221102141014.1025893-1-Frank.Li@nxp.com>

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().
