From: Ville Syrjälä Date: Tue, 8 Dec 2015 16:41:53 +0000 (+0200) Subject: drm: Add crtc->name and use it in debug messages X-Git-Tag: v4.9.8~2860^2~32^2~10 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fa3ab4c2113c74a9eae9b6a718b167f7c8833e78;p=platform%2Fkernel%2Flinux-rpi3.git drm: Add crtc->name and use it in debug messages Show a sensible name for the crtc in debug mesages. The driver may supply its own name, otherwise the core genrates the name ("crtc-0", "crtc-1" etc.). v2: kstrdup() the name passed by the caller (Jani) v3: Generate a default name if the driver doesn't supply one Signed-off-by: Ville Syrjälä Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/1449592922-5545-6-git-send-email-ville.syrjala@linux.intel.com --- diff --git a/drivers/gpu/drm/drm_atomic.c b/drivers/gpu/drm/drm_atomic.c index 07ab75e..feb6689 100644 --- a/drivers/gpu/drm/drm_atomic.c +++ b/drivers/gpu/drm/drm_atomic.c @@ -288,8 +288,8 @@ drm_atomic_get_crtc_state(struct drm_atomic_state *state, state->crtcs[index] = crtc;
