Subject: watchdog: ixp4xx_wdt: Fix address space warning
Git-commit: abd1c6adc16d1b82109a29b570fc545b775049d5
Patch-mainline: v5.15
References: bsc#1208619
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.
