From 44adece57e2604cec8527a499b48e4d584ab53b8 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 10 Aug 2016 18:52:34 +0200 Subject: [PATCH] drm/fb-helper: Add a dummy remove_conflicting_framebuffers MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Lots of drivers don't properly compile without this when CONFIG_FB=n. It's kinda a hack, but since CONFIG_FB doesn't stub any fucntions when it's disabled I think it makes sense to add it to drm_fb_helper.h. Long term we probably need to rethink all the logic to unload firmware framebuffer drivers, at least if we want to be able to move away from CONFIG_FB and fbcon. v2: Unfortunately just stubbing out remove_conflicting_framebuffers in drm_fb_helper.h upset gcc about static vs. non-static declarations, so a new wrapper it needs to be. Means more churn :( Cc: Tobias Jakobi Cc: Noralf Trønnes Cc: tomi.valkeinen@ti.com Cc: dh.herrmann@gmail.com Reviewed-by: Alex Deucher Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/1470847958-28465-2-git-send-email-daniel.vetter@ffwll.ch --- drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c | 2 +- drivers/gpu/drm/bochs/bochs_drv.c | 3 ++- drivers/gpu/drm/cirrus/cirrus_drv.c | 2 +- drivers/gpu/drm/i915/i915_drv.c | 2 +- drivers/gpu/drm/mgag200/mgag200_drv.c | 2 +- drivers/gpu/drm/mgag200/mgag200_main.c | 2 +- drivers/gpu/drm/nouveau/nouveau_drm.c | 2 +- drivers/gpu/drm/radeon/radeon_drv.c | 3 ++- drivers/gpu/drm/sun4i/sun4i_drv.c | 3 ++- drivers/gpu/drm/vc4/vc4_drv.c | 3 ++- drivers/gpu/drm/virtio/virtgpu_drm_bus.c | 3 ++- include/drm/drm_fb_helper.h | 14 ++++++++++++++ 12 files changed, 30 insertions(+), 11 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c index 9aa533cf4ad1..11263c5b9967 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c @@ -341,7 +341,7 @@ static int amdgpu_kick_out_firmware_fb(struct pci_dev *pdev) #ifdef CONFIG_X86 primary = pdev->resource[PCI_ROM_RESOURCE].flags & IORESOURCE_ROM_SHADOW;
