Re: [PATCH 04/14] mfd: remove unused wm8400 driver

From: Arnd Bergmann <arnd@arndb.de>

This driver requires a platform_data definition, which does not exist
in the kernel.

According to Mark Brown, the hardware supported by this driver was never
shipped in production.

Since this is clearly unused, remove it.

Signed-off-by: Arnd Bergmann <arnd@arndb.de>
