Subject: drm: fix fbs in DRM_IOCTL_MODE_GETRESOURCES ioctl
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=618c75e491a5a50cd3819eaf5f853fd87df3ae42;p=linux-beck.git

drm: fix fbs in DRM_IOCTL_MODE_GETRESOURCES ioctl

The DRM_IOCTL_MODE_GETRESOURCES ioctl just returns bogus framebuffers.
That is because the framebuffers for each file are in the filp_head
member of struct drm_framebuffer, not in the head member.
