[PATCH] Driver core: export platform_device_register_data as a GPL symbol

[PATCH] Driver core: export platform_device_register_data as a GPL symbol

[Mike Frysinger]

From: Michael Hennerich <michael.hennerich@analog.com>

This allows MFD's to register/bind drivers for their sub devices while
still being compiled as a module.

Is this a problem that we need to get resolved in .33, or older kernels,
or just for .34?

thanks,

the functionality is in place now, so it could be used in .33.  but it
isnt that big of a deal to simply say the mfd core cant be built as a
module right now.

so, it'd be nice for .33, but if it's too much hassle, .34 is OK.

Ok, I'll queue it up for .33, as it keeps an in-kernel driver from
working properly now.
