Hello!
This series contains fixes to the kernel related to the semantics

header comment.

The section of memory-barriers.txt that describes the dma_Xmb() barriers
has an incorrect example claiming that a wmb() is required after writing
to coherent memory in order for those writes to be visible to a device

This patchs adds the cec_notifier feature to the intel_hdmi part
of the i915 DRM driver. It uses the HDMI DRM connector name to differentiate
between each HDMI ports.
The changes will allow the i915 HDMI code to notify EDID and HPD changes
to an eventual CEC adapter.

In non device-tree world, we can need to get the notifier by the driver

This patch adds a variant of the get function by using the device name
instead and will not create a notifier if not yet created.
