As the code is currently written, if read_smc_arg were ever NULL, arg
would fail to be initialized but the code would continue executing as
normal because the return value would just be zero.
There are a few different possible solutions to resolve this class
of warnings which have appeared in these drivers before:
1. Assume the function pointer will never be NULL and eliminate the
wrapper macros.
2. Have the wrapper macros initialize arg when the function pointer is
NULL.
3. Have the wrapper macros return an error code instead of 0 when the
function pointer is NULL so that the callsites can properly bail out
before arg can be used.
4. Initialize arg at the top of its function.
Number four is the path of least resistance right now as every other
change will be driver wide so do that here. I only make the comment
now as food for thought.

drm/amd/display: Block immediate flips for non-fast updates
[Why]
Underflow can occur in the case where we change buffer pitch, DCC state,
rotation or mirroring for a plane while also performing an immediate
flip. It can also generate a p-state warning stack trace on DCN1 which
is typically observed during the cursor handler pipe locking because of
how frequent cursor updates can occur.
[How]
Store the update type on each CRTC - every plane will have access to
the CRTC state if it's flipping. If the update type is not
UPDATE_TYPE_FAST then the immediate flip should be disallowed.
No changes to the target vblank sequencing need to be done, we just
need to ensure that the surface registers do a double buffered update.

drm/amd/display: Validate dc_plane_info and dc_plane_size in atomic check
[Why]
Pitch, DCC, rotation and mirroring can result in updates that are not
UPDATE_TYPE_FAST but UPDATE_TYPE_MED instead. DC needs dc_plane_info
and dc_plane_size to make this determination and we aren't currently
passing this into DC during atomic check.
Underflow (visible or non-visible) can occur if we don't validate this
correctly. This also will generally trigger p-state warnings, typically
via the cursor handler when locking.
[How]
Get the framebuffer tiling flags and generate the required structures
for DC in dm_determine_update_type_for_commit.

drm: Add Content protection type property
This patch adds a DRM ENUM property to the selected connectors.
This property is used for mentioning the protected content's type
from userspace to kernel HDCP authentication.
Type of the stream is decided by the protected content providers.
Type 0 content can be rendered on any HDCP protected display wires.
But Type 1 content can be rendered only on HDCP2.2 protected paths.
So when a userspace sets this property to Type 1 and starts the HDCP
enable, kernel will honour it only if HDCP2.2 authentication is through
for type 1. Else HDCP enable will be failed.
