From c9a129966227b39ec5f03abd4e24c8c08ee010ac Mon Sep 17 00:00:00 2001 From: Mark Hounschell Date: Fri, 28 Mar 2014 09:30:15 -0400 Subject: [PATCH] staging: dgap: rename and fixup dgap_wait_for_xxx functions This patch renames and changes the dgap_wait_for_bios and dgap_wait_for_fep functions from boolean functions to return zero on success and a negative error code on error.
