sparse reports the following address space warning.
drivers/watchdog/ixp4xx_wdt.c:122:20: sparse: incorrect type in assignment (different address spaces) drivers/watchdog/ixp4xx_wdt.c:122:20: sparse: expected void [noderef] __iomem *base drivers/watchdog/ixp4xx_wdt.c:122:20: sparse: got void *platform_data
Add a typecast to solve the problem.
