From fec6c4e0e7967ad67b7f97fa3183b33bf794b3e6 Mon Sep 17 00:00:00 2001 From: Mark Hounschell Date: Wed, 19 Feb 2014 13:12:06 -0500 Subject: [PATCH] staging: dgap: Merge dgap_fep5.h into dgap_driver.h There is a lot of cleanup work to do on these digi drivers and merging as much as is possible will make it easier. I also notice that many merged drivers are single source and header.
