ACPI: sysfs: Make sparse happy about address space in use
Sparse is not happy about address space in use in acpi_data_show(): drivers/acpi/sysfs.c:428:14: warning: incorrect type in assignment (different address spaces) drivers/acpi/sysfs.c:428:14: expected void [noderef] __iomem *base drivers/acpi/sysfs.c:428:14: got void * drivers/acpi/sysfs.c:431:59: warning: incorrect type in argument 4 (different address spaces) drivers/acpi/sysfs.c:431:59: expected void const *from drivers/acpi/sysfs.c:431:59: got void [noderef] __iomem *base drivers/acpi/sysfs.c:433:30: warning: incorrect type in argument 1 (different address spaces) drivers/acpi/sysfs.c:433:30: expected void *logical_address drivers/acpi/sysfs.c:433:30: got void [noderef] __iomem *base Indeed, acpi_os_map_memory() returns a void pointer with dropped specific address space. Hence, we don't need to carry out __iomem in acpi_data_show(). Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
