Hi all,

After merging the watchdog tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/watchdog/lenovo_se30_wdt.c: In function 'lenovo_se30_wdt_probe':
drivers/watchdog/lenovo_se30_wdt.c:272:31: error: implicit declaration of function 'devm_ioremap' [-Wimplicit-function-declaration]
272 | priv->shm_base_addr = devm_ioremap(dev, base_phys, SHM_WIN_SIZE);
| ^~~~~~~~~~~~
drivers/watchdog/lenovo_se30_wdt.c:272:29: error: assignment to 'unsigned char *' from 'int' makes pointer from integer without a cast [-Wint-conversion]
272 | priv->shm_base_addr = devm_ioremap(dev, base_phys, SHM_WIN_SIZE);
| ^

Caused by commit

c284153a2c55 ("watchdog: lenovo_se30_wdt: Watchdog driver for Lenovo SE30 platform")

Somewhere alogn the way a change to some include file means that
linux/io.h is no longer implicitly included. I have added the following
patch for today.
