Subject: [patch 1/5] Add comments to the PDA structure to annotate offsets From: Arjan van de Ven <arjan@linux.intel.com>
Change the comments in the pda structure to make the first fields to have their offset documented (the rest of the fields follows in a later patch) and to have the comments aligned.
