From 9f0ac028410fe8ad3aa2a9d82fa1cfc9ebba70ac Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Mon, 28 Oct 2019 12:38:18 +0200 Subject: [PATCH] drm/print: rename drm_debug to __drm_debug to discourage use MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit drm_debug_enabled() is the way to check. __drm_debug is now reserved for drm print code only. No functional changes. v2: Rebase on move unlikely() to drm_debug_enabled() Acked-by: Alex Deucher Reviewed-by: Eric Engestrom Acked-by: Ville Syrjälä Acked-by: Sean Paul Signed-off-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/840ff7292d1a39512bac2fcb1f45de9d50694bf1.1572258936.git.jani.nikula@intel.com --- drivers/gpu/drm/drm_print.c | 8 ++++---- include/drm/drm_print.h | 5 +++-- 2 files changed, 7 insertions(+), 6 deletions(-) diff --git a/drivers/gpu/drm/drm_print.c b/drivers/gpu/drm/drm_print.c index 9a25d73..a0d1cde 100644 --- a/drivers/gpu/drm/drm_print.c +++ b/drivers/gpu/drm/drm_print.c @@ -37,11 +37,11 @@ #include /* - * drm_debug: Enable debug output. + * __drm_debug: Enable debug output. * Bitmask of DRM_UT_x.
