      drm/dp/mst: close deadlock in connector destruction. · 6b8eeca6
      Dave Airlie authored 
      

I've only seen this once, and I failed to capture the
lockdep backtrace, but I did some investigations.

If we are calling into the MST layer from EDID probing,
we have the mode_config mutex held, if during that EDID
probing, the MST hub goes away, then we can get a deadlock
where the connector destruction function in the driver
tries to retake the mode config mutex.

This offloads connector destruction to a workqueue,
and avoid the subsequenct lock ordering issue.

      drm: Always enable atomic API · 8b72ce15
      Daniel Stone authored 
      

Now that the interface has been proven by a port of Weston (using all
atomic features including TEST_ONLY), remove the module parameter
guarding the atomic API from being exposed, and let it run free in the
wild.

      drm/vgem: Set unique to "vgem" · fa2f97dd
      Daniel Vetter authored 
      

Since there's only one global instance ever we don't need to have
anything fancy. Stops a WARNING in the get_unique ioctl that the
unique name isn't set.

This patch fixes the below build error reported by Stephen,

     Stephen reported:
     After merging the drm-exynos tree, today's linux-next build (x86_64
     allmodconfig) failed like this:

     Caused by commit:
       a0f7001c18ca ("of: add helper for getting endpoint node of specific identifiers")

To fix the error, this patch declares of_graph_get_endpoint_by_regs function
with "static inline".
