Hi Samuel,

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

drivers/mfd/wm831x-core.c: In function 'wm831x_device_init':
drivers/mfd/wm831x-core.c:1507:12: error: 'WM831X_XTAL_ENA' undeclared (first use in this function)

Caused by commit e1af6eaa2160 ("mfd: Only register wm831x RTC device if
the 32.768kHz crystal is enabled").

I have used the mfd tree from next-20110620 for today.
