Subject: [PATCH 19/27] mfd: remove ucb1400 support
From: Arnd Bergmann <arnd@...db.de>
The ucb1400 MFD driver and its gpio and touchscreen child
drivers were only used on a few PXA machines that were unused
for a while and are now removed.
Removing these leaves the AC97 support as ALSA specific,
no other drivers are now connected through this interface.
