Now that all this code is gone do we have a user of the
msm_ssbi_platform_data struct? Why not remove it from the header file?
If you remove it from the header you can probably move the enum for
controller_type into this file too.

This could be dev_err() considering you use dev_info() below.

dev_err()?

const?
