      drm/shmobile: Fix race condition between page flip request and handler · 17f0efc4
      Laurent Pinchart authored 
      The page flip handler stores the page flip event pointer and then calls
drm_vblank_get() to enable the vblank interrupt. Due to the vblank off
delay, the vblank interrupt can be enabled in the hardware at that
point, even if the vblank reference count is equal to 0. If a vblank
interrupt is triggered between storing the event pointer and calling
drm_vblank_get(), the page flip completion handler will process the
event and call drm_vblank_put() with a reference count equal to 0. This
will result in a BUG_ON.

Fix the race condition by calling drm_vblank_get() before storing the
event pointer.

      drm: export drm_vm_open_locked · d5028995
      Arnd Bergmann authored 
      The EXYNOS DRM driver uses drm_vm_open_locked in its mmap() function,
and it can be built as a loadable module, which currently fails.
This exports the symbol from the DRM core to avoid

ERROR: "drm_vm_open_locked" [drivers/gpu/drm/exynos/exynosdrm.ko] undefined!

      drm/tilcdc: use only a single module device table · a59e1ff3
      Arnd Bergmann authored 
      The tilcdc driver fails to be built as a module because of extraneous
MODULE_DEVICE_TABLE entries:

drivers/gpu/drm/tilcdc/tilcdc_slave.o:(.data+0x54): multiple definition of `__mod_of_device_table'
drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here
drivers/gpu/drm/tilcdc/tilcdc_panel.o:(.data+0x54): multiple definition of `__mod_of_device_table'
drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here
drivers/gpu/drm/tilcdc/tilcdc_drv.o:(.data+0x184): multiple definition of `__mod_of_device_table'
drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here

Since the entire point of these entries is to make the module autoload
when one of the devices is present, it's enough to keep the one entry
for "ti,am33xx-tilcdc", which should always be there if any of the
others are.

      Merge branch 'gma500-fixes' of git://github.com/patjak/drm-gma500 into drm-next · 84806ade
      Dave Airlie authored 
      Two fixes for gma500. First one from Anisse allows us to handle ASLE irqs even
when BIOS doesn't trigger a pipe event irq. The second one allows dual head
setups to have a big shared framebuffer.

* 'gma500-fixes' of git://github.com/patjak/drm-gma500:
  drm/gma500: Increase max resolution for mode setting
  drm/gma500: fix backlight hotkeys behaviour on netbooks
