From 86e6325e5ab848c15c422f20133445fe6c1caa09 Mon Sep 17 00:00:00 2001
From: Eric Anholt <anholt@freebsd.org>
Date: Wed, 22 Oct 2003 22:08:53 +0000
Subject: - Add DRM_GET_PRIV_WITH_RETURN macro. This can be used in shared code
to get the drm_file_t * based on the filp passed in ioctl handlers. - Use
this macro on BSD for simplification and improve its error reporting.
Make failure to find the drm_file_t * print as an error, not debug. This
failure may be part of the problem with KDE. - Make debug and error print
macros include the pid on BSD.
