Hi Greg,

After merging the driver-core tree, today's linux-next build (powerpc
allnoconfig) failed like this:

drivers/base/dd.c: In function 'driver_allows_async_probing':
drivers/base/dd.c:430:31: error: dereferencing pointer to incomplete type
   if (drv->owner && drv->owner->async_probe_requested)
                               ^

Caused by commit f2411da74698 ("driver-core: add driver module
asynchronous probe support").

I have applied the following fix patch for today:

Subject: [PATCH] driver-core: add driver module asynchronous probe support fix

struct module is not defined if CONFIG_MODULES is not set.
