Hmpf, these give me a few new warnings related to this series:

make W=1 drivers/platform/x86/
make C=2 drivers/platform/x86/

...I really don't know why sparse complains about the lock context

There's also a copy-paste error:

 * lwmi_gz_profile_get_get() - Get the current platform profile.

..._get_get -> ..._set
Get -> Set
