2020-11-19mm: mmap: fix fput in error path v2Christian König
Patch "495c10cc1c0c CHROMIUM: dma-buf: restore args..." adds a workaround for a bug in mmap_region. As the comment states ->mmap() callback can change vma->vm_file and so we might call fput() on the wrong file. Revert the workaround and proper fix this in mmap_region. v2: drop the extra if in dma_buf_mmap as well Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Jason Gunthorpe <jgg@nvidia.com> Acked-by: Andrew Morton <akpm@linux-foundation.org> Link: https://patchwork.freedesktop.org/patch/399359/
2020-11-18char/agp: Disable frontend without CONFIG_DRM_LEGACYDaniel Vetter
It's probably full of bugs ready for exploiting by userspace. And there's not going to be any userspace for this without any of the drm legacy drivers enabled too. So just couple it together. Note that the frontend is only the /dev/agp ioctl interface, which per Adam is only used by the i810 userspace drivers. All other drivers go through the drm bufmap agp handling abstraction apparently. v2: Augment commit message a bit from m-l feedback.

2020-11-17drm/meson: dw-hdmi: Ensure that clocks are enabled before touching the TOP ↵Marc Zyngier
registers Removing the meson-dw-hdmi module and re-inserting it results in a hang as the driver writes to HDMITX_TOP_SW_RESET. Similar effects can be seen when booting with mainline u-boot and using the u-boot provided DT (which is highly desirable). The reason for the hang seem to be that the clocks are not always enabled by the time we enter meson_dw_hdmi_init(). Moving this call *after* dw_hdmi_probe() ensures that the clocks are enabled.
