Dropping platform_set_drvdata seems to me like it should
be a separate patch.
And are you sure no other function uses a get_drvdata call?
Maybe something in watchdog_dev.c? Possibly:
#ifdef CONFIG_WATCHDOG_SYSFS
static ssize_t nowayout_show(struct device *dev, struct device_attribute
*attr,
char *buf)
{
struct watchdog_device *wdd = dev_get_drvdata(dev);
return sprintf(buf, "%d\n", !!test_bit(WDOG_NO_WAY_OUT, &wdd->status));
}
static DEVICE_ATTR_RO(nowayout);
