The function mod_hdcp_hdcp1_enable_encryption() calls the function
get_first_active_display(), but does not check its return value.
The return value is a null pointer if the display list is empty.
This will lead to a null pointer dereference in
mod_hdcp_hdcp2_enable_encryption().
Add a null pointer check for get_first_active_display() and return
MOD_HDCP_STATUS_DISPLAY_NOT_FOUND if the function return null.

V3: drop changes where readbacks have implemented. This patch set
is to add readbacks only.
V2: use common register UVD_STATUS for readback (standard PCI MMIO
behavior, i.e. readback post all writes to let the writes hit
the hardware)
add readback in ..._stop() for more coverage.
Similar to the changes made for VCN v4.0.5 where readback to post the
writes to avoid race with the doorbell, the addition of register
readback support in other VCN versions is intended to prevent potential
race conditions, even though such issues have not been observed yet.
This change ensures consistency across different VCN variants and helps
avoid similar issues. The overhead introduced is negligible.

Dealing with CCS state is significant on LNL+, where we end up clearing
the compression state on every page alloc using the blitter for user
buffers, including also saving and restoring it when moving between
domains, plus we need to alloc extra pages to hold the raw CCS state for
the save step.
However all compression PAT modes, on platforms like LNL, also require
coh_none, meaning that only WC memory can use compression in the first
place. With this we can be sneaky and completely ignore CCS for WB
buffers, which is likely the common case anyway. This would then skip
all blitter moves/clears between sys <-> tt and then also means we can
drop the extra CCS pages.
This should be safe since there is no way to interact with the
compression state (potentially uncleared) without using a PAT enabled
index (which is rejected at bind), including if trying to be malicious
and copy the raw CCS state from userpace, which should give back all
zeroes if the src surface (indirect) is lacking compressed PAT index.

Today we allow to trigger GT resest by reading dedicated debugfs
files "force_reset" and "force_reset_sync" that we are exposing
using drm_info_list[] and drm_debugfs_create_files().
To avoid triggering potentially disruptive actions during otherwise
"safe" read operations, expose those two attributes using debugfs
function where we can specify file permissions and provide custom
"write" handler to trigger the GT resets also from there.
This step would allow us to drop triggering GT resets during read
operations, which we leave just to give users more time to switch.

Pull drm updates from Dave Airlie:
"As part of building up nova-core/nova-drm pieces we've brought in some
rust abstractions through this tree, aux bus being the main one, with
devres changes also in the driver-core tree. Along with the drm core
abstractions and enough nova-core/nova-drm to use them. This is still
all stub work under construction, to build the nova driver upstream.
The other big NVIDIA related one is nouveau adds support for
Hopper/Blackwell GPUs, this required a new GSP firmware update to
570.144, and a bunch of rework in order to support multiple fw
interfaces.
There is also the introduction of an asahi uapi header file as a
precursor to getting the real driver in later, but to unblock
userspace mesa packages while the driver is trapped behind rust
enablement.
Otherwise it's the usual mixture of stuff all over, amdgpu, i915/xe,
