From dc4a109474c6bffacaf754440fa88ff0dd957667 Mon Sep 17 00:00:00 2001 From: Ander Conselvan de Oliveira Date: Thu, 2 Mar 2017 14:58:54 +0200 Subject: [PATCH] drm/i915: Pass pipe_config to fdi_link_train() functions MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit It is preferred to pass pipe_config to functions instead of accessing crtc->config directly. Follow suit and pass pipe_config to the fdi link train functions. v2: Add const; s/pipe_config/crtc_state/ (Ville) Signed-off-by: Ander Conselvan de Oliveira Reviewed-by: Ville Syrjälä Link: http://patchwork.freedesktop.org/patch/msgid/20170302125857.14665-5-ander.conselvan.de.oliveira@intel.com --- drivers/gpu/drm/i915/i915_drv.h | 3 ++- drivers/gpu/drm/i915/intel_ddi.c | 9 +++++---- drivers/gpu/drm/i915/intel_display.c | 19 +++++++++++-------- drivers/gpu/drm/i915/intel_drv.h | 3 ++- 4 files changed, 20 insertions(+), 14 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_drv.h b/drivers/gpu/drm/i915/i915_drv.h index b25c1df05145..07bf2e32ffa7 100644 --- a/drivers/gpu/drm/i915/i915_drv.h +++ b/drivers/gpu/drm/i915/i915_drv.h @@ -669,7 +669,8 @@ struct drm_i915_display_funcs { struct intel_encoder *encoder, const struct drm_display_mode *adjusted_mode);
