From 5598e55a8dc647c4c4ea474351f85b93d9e9dd68 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Thu, 31 Aug 2017 17:03:17 +0200 Subject: staging: vboxvideo: Use CONFIG_DRM_KMS_FB_HELPER to check for fbdefio availability Checking for CONFIG_FB_DEFERRED_IO is not the right thing to do since the fbdev code may be built as a module while vboxvideo is builtin. This can only happen when DRM_KMS_FB_HELPER is not set: a) DRM_VBOXVIDEO selects DRM_KMS_HELPER b) DRM_KMS_FB_HELPER depends on DRM_KMS_HELPER c) DRM_KMS_FB_HELPER selects FB_DEFERRED_IO So when DRM_KMS_FB_HELPER is set and vboxvideo is builtin then FB_DEFERRED_IO must be builtin too. This commit moves the #ifdefs around fbdefio code over to CONFIG_DRM_KMS_FB_HELPER, as other drm drivers already do, fixing: drivers/staging/vboxvideo/vbox_fb.o: In function `vbox_fbdev_fini': vbox_fb.c:(.text+0x36): undefined reference to `fb_deferred_io_cleanup' Signed-off-by: Hans de Goede Signed-off-by: Greg Kroah-Hartman --- drivers/staging/vboxvideo/vbox_fb.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'drivers/staging') diff --git a/drivers/staging/vboxvideo/vbox_fb.c b/drivers/staging/vboxvideo/vbox_fb.c index a85797b45ecf..8aed248db6e2 100644 --- a/drivers/staging/vboxvideo/vbox_fb.c +++ b/drivers/staging/vboxvideo/vbox_fb.c @@ -45,7 +45,7 @@ #include "vbox_drv.h" #include "vboxvideo.h" -#ifdef CONFIG_FB_DEFERRED_IO +#ifdef CONFIG_DRM_KMS_FB_HELPER static struct fb_deferred_io vbox_defio = { .delay = HZ / 30, .deferred_io = drm_fb_helper_deferred_io, @@ -173,7 +173,7 @@ static int vboxfb_create(struct drm_fb_helper *helper, info->screen_base = bo->kmap.virtual; info->screen_size = size; -#ifdef CONFIG_FB_DEFERRED_IO +#ifdef CONFIG_DRM_KMS_FB_HELPER info->fbdefio = &vbox_defio; fb_deferred_io_init(info); #endif @@ -195,7 +195,7 @@ void vbox_fbdev_fini(struct drm_device *dev) struct vbox_fbdev *fbdev = vbox->fbdev; struct vbox_framebuffer *afb = &fbdev->afb; -#ifdef CONFIG_FB_DEFERRED_IO +#ifdef CONFIG_DRM_KMS_FB_HELPER if (fbdev->helper.fbdev && fbdev->helper.fbdev->fbdefio) fb_deferred_io_cleanup(fbdev->helper.fbdev); #endif -- cgit v1.2.3
