ACPI: OSL: fix __iomem type on return from acpi_os_map_generic_address()
[ Upstream commit 393815f57651101f1590632092986d1d5a3a41bd ]
The pointer returned from acpi_os_map_generic_address() is
tagged with __iomem, so make the rv it is returned to also
of void __iomem * type.
Fixes the following sparse warning:
drivers/acpi/osl.c:1686:20: warning: incorrect type in assignment (different address spaces)
drivers/acpi/osl.c:1686:20: expected void *rv
drivers/acpi/osl.c:1686:20: got void [noderef] __iomem *
Fixes: 6915564dc5a8 ("ACPI: OSL: Change the type of acpi_os_map_generic_address() return value")
