There's now at least these two:

- "drm/radeon: use fixed PPL ref divider if needed"
that look like fairly fatal regressions when they affect somebody.

That is not possible. Because the bridge callbacks are called in this
fashion:
bridge->funcs->post_disable(bridge);
So, if that particular callback turns NULL, it will crash!

Certain bridge chips use a GPIO to indicate the cable status instead
of the I_DP_HPD pin. This adds an optional device-tree property,

the specified GPIO should be used for hotplug detection.
The GPIO is

powerup/down routines needed to support eDP/eDP-LVDS panels

The LCD and LED units are usually powered up via regulators,

Use %pad for dma_addr_t, because a dma_addr_t type can vary
based on build options. So, it prevents possible build warnings

The way the tile mode array index was calculated only makes sense for
the CIK specific macrotile mode array. For SI, we need to use one of the
tile mode array indices reserved for displayable surfaces.
This happened to result in correct display most if not all of the time

I've just worked on a massive patch series to rework the haswell WRPLL. It
kills the hsw specific shared pll framework and swi
rnel
will keep growing in size until it no longer fits in any kind of memory.

arcane rules and slight differences between ->update_plane and
