From a1f1a79c51fd493887bb66d932ee66a23f8b1527 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Sat, 11 Oct 2014 22:08:57 -0700 Subject: [PATCH] drm: drm_err: Remove unnecessary __func__ argument Removing the unnecessary drm_err __func__ argument by using the equivalent %pf and __builtin_return_address(0) makes the code smaller for every use of the DRM_ERROR macro.
