usb: host: oxu210hp-hcd: fix __iomem annotations
There are a number of places in the driver where it fails to maintain __iomem on pointers used to access registers so fixup the warnings by adding these in the appropriate places. Examples of the sparse warnings fixed: drivers/usb/host/oxu210hp-hcd.c:686:9: warning: incorrect type in argument 2 (different address spaces) drivers/usb/host/oxu210hp-hcd.c:686:9: expected void volatile [noderef] <asn:2> *addr drivers/usb/host/oxu210hp-hcd.c:686:9: got void * drivers/usb/host/oxu210hp-hcd.c:686:9: warning: incorrect type in argument 2 (different address spaces) drivers/usb/host/oxu210hp-hcd.c:686:9: expected void volatile [noderef] <asn:2> *addr drivers/usb/host/oxu210hp-hcd.c:686:9: got void * drivers/usb/host/oxu210hp-hcd.c:686:9: warning: incorrect type in argument 2 (different address spaces) drivers/usb/host/oxu210hp-hcd.c:686:9: expected void volatile [noderef] <asn:2> *addr drivers/usb/host/oxu210hp-hcd.c:686:9: got void * drivers/usb/host/oxu210hp-hcd.c:681:16: warning: incorrect type in argument 1 (different address spaces) drivers/usb/host/oxu210hp-hcd.c:681:16: expected void const volatile [noderef] <asn:2> *addr drivers/usb/host/oxu210hp-hcd.c:681:16: got void * Signed-off-by: Ben Dooks <ben.dooks@codethink.co.uk> Link: https://lore.kernel.org/r/20191017171934.8771-1-ben.dooks@codethink.co.uk Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
