Seems to be due to a bad merge. Code was originally added in
commit 5aaa8fff3a ("drm/amd/powerplay: unload mp1 for Arcturus RAS baco reset")
but later removed in commit 7f70443fd8 ("drm/amdgpu: set mp1 state before reload").
but is back again.

All of the drivers in the kernel tree only call this from one of the
following contexts:
* drm_crtc_funcs->reset
* During initial module load
Since both of these contexts are guaranteed to have interrupts enabled
beforehand, there's no need to use the irqsave/irqrestore variants of
spin_(un)lock(). So, fix this to make the irq context of this function
more obvious.

The original intention was to avoid CPU page table unmaps
when BOs move between the GTT and SYSTEM domain.
The problem is that this never correctly handled changes
in the caching attributes or backing pages.
Just drop this for now and simply unmap the CPU page
tables in all cases.

Nouveau is the only user of this functionality and evicting io space
on -EAGAIN is really a misuse of the return code.
Instead switch to using -ENOSPC here which makes much more sense and
simplifies the code.
This could unbreak something as we now cleanly return EAGAIN, but the
chance for this are rather low.

Use a bit-mask of EOF irqs to determine when all required idmac
channel EOFs have been received for a tile conversion, and only do
tile completion processing after all EOFs have been received. Otherwise
it was found that a conversion would stall after the completion of a
tile and the start of the next tile, because the input/read idmac
channel had not completed and entered idle state, thus locking up the
channel when attempting to re-start it for the next tile.

The bus_flags handling logic does not seem to cover all potential
usecases. Specifically, this seems to fail with an "edt,etm0700g0edh6"
display attached to an 24bit display interface, with interface-pix-fmt
= "rgb24" set in DT.
This patch fixes the problem by overriding the imx_crtc_state->bus_flags
from the imxpd->bus_flags only if the DT property "interface-pix-fmt" is
present or if the DI provides no formats.

Component driver structures allocated with devm_kmalloc() in bind() are
freed automatically after unbind(). Since the contained drm structures
are accessed afterwards in drm_mode_config_cleanup(), move the
allocation into probe() to extend the driver structure's lifetime to the
lifetime of the device. This should eventually be changed to use drm
resource managed allocations with lifetime of the drm device.
We also need to ensure that all componets are available during the
unbind() so we need to call component_unbind_all() before we free
non-devres resources like planes.
Note this patch fixes the the use after free bug but introduces a
possible boot loop issue. The issue is triggered if the HDMI support is
enabled and a component driver always return -EPROBE_DEFER, see
discussion [1] for more details.
