PCI: iproc-msi: Fix __iomem annotation in decode_msi_hwirq()
Fix __iomem attribute on msg variable passed to readl() in the decode_msi_hwirq() function. Fixes the following sparse warning: drivers/pci/controller/pcie-iproc-msi.c:301:17: warning: incorrect type in argument 1 (different address spaces) drivers/pci/controller/pcie-iproc-msi.c:301:17: expected void const volatile [noderef] <asn:2> *addr drivers/pci/controller/pcie-iproc-msi.c:301:17: got unsigned int [usertype] *[assigned] msg Signed-off-by: Ben Dooks <[email protected]> Signed-off-by: Lorenzo Pieralisi <[email protected]> Cc: Lorenzo Pieralisi <[email protected]> Cc: Andrew Murray <[email protected]> Cc: Bjorn Helgaas <[email protected]> Cc: Ray Jui <[email protected]> Cc: Scott Branden <[email protected]> Cc: [email protected] Cc: [email protected] Cc: [email protected] Cc: [email protected]
