The Subsystem ID is read from the HDA driver, and will
be used by the CS35L41 driver to be able to uniquely
identify the laptop, which is required to be able to
define firmware to be used by specific models.

Wouldn't comps->codec->core.subsystem_id instead of comps->subsystem_id 
work here? You already added saving of codec in patch 3, and then you 
don't need rest of this patch?
