I'm not exactly clear on what strange workflow causes people to do it,
but clearly occasionally some files end up being committed as executable
even though they clearly aren't.
This is a reprise of commit 90fda63fa115 ("treewide: fix up files
incorrectly marked executable"), just with a different set of files (but
with the same trivial shell scripting).
So apparently we need to re-do this every five years or so, and Joe
needs to just keep reminding me to do so ;)

Use the RUNTIME_PM_OPS() and pm_ptr() macros to handle the
.runtime_suspend/.runtime_resume callbacks.
These macros allow the suspend and resume functions to be automatically
dropped by the compiler when CONFIG_PM is disabled, without having
to use #ifdef guards.
This has the advantage of always compiling these functions in,
independently of any Kconfig option. Thanks to that, bugs and other
regressions are subsequently easier to catch.

Currently all fences have a 30 second timeout to ensure they are
cleaned up if the fence never completes otherwise. However, this
one size fits all solution doesn't actually fit in every case,
such as syncpoint waiting where we want to be able to have timeouts
longer than 30 seconds. As such, we want to be able to give control
over fence cancellation to the caller (and maybe eventually get rid
of the internal timeout altogether).
Here we add this cancellation mechanism by essentially adding a
function for entering the timeout path by function call, and changing
the syncpoint wait function to use it.

Move from the old, complex intr handling code to a new implementation

In anticipation of removal of the intr API, implement job tracking

making cdma_update schedule the work since fence completion can

It's a bit confusing to have two cached EDIDs in struct intel_connector
with slightly different purposes. Make the distinction a bit clearer by
moving the EDID cached for eDP and LVDS panels at connector init time to
struct intel_panel, and name it fixed_edid. That's what it is, a fixed
EDID for the panels.

Convert all the connectors that use cached connector edid and
detect_edid to drm_edid.
Since drm_get_edid() calls drm_connector_update_edid_property() while
drm_edid_read*() do not, we need to call drm_edid_connector_update()
separately, in part due to the EDID caching behaviour in HDMI and
DP. Especially DP depends on the details parsed from EDID. (The big
behavioural change conflating EDID reading with parsing and property
update was done in commit 5186421cbfe2 ("drm: Introduce epoch counter to

For uninitialized framebuffers, only release the DRM client and
free the fbdev memory. Do not attempt to clean up the framebuffer.
DRM fbdev clients have a two-step initialization: first create
the DRM client; then create the framebuffer device on the first
successful hotplug event. In cases where the client never creates
the framebuffer, only the client state needs to be released. We
can detect which case it is, full or client-only cleanup, by
looking at the presence of fb_helper's info field.

Signal failed hotplugging with a flag in struct drm_client_dev. If set,
the client helpers will not further try to set up the fbdev display.
This used to be signalled with a combination of cleared pointers in
struct drm_fb_helper, which prevents us from initializing these pointers
early after allocation.
The change also harmonizes behavior among DRM clients. Additional DRM
clients will now handle failed hotplugging like fbdev does.

The current design of callback function disable() of struct
nvkm_devinit_func is defined to return a u64 value. In its implementation
in the driver modules, the function always returns a fixed value 0. Hence
the design and implementation of this function should be enhanced to return
void instead of a fixed value. This change also eliminates untouched
return variables.

Switching between certain modes that are freesync video modes and those

The issue is fixed by ensuring that when a non freesync video mode is
set, we reset the freesync status on the crtc.

by calling dm_helpers_dp_mst_write_payload_allocation_table().
Currently, it get modified to try to update HW payload table

This is just a quick workaround. Should find way to remove the
temporary struct dc_dp_mst_stream_allocation_table later if set
struct link_mst_stream_allocatio directly is possible.

Looks like I made a pretty big mistake here without noticing: it seems when
I moved the assignments of mst_state->pbn_div I completely missed the fact
that the reason for us calling drm_dp_mst_update_slots() earlier was to
account for the fact that we need to call this function using info from the
root MST connector, instead of just trying to do this from each MST
encoder's atomic check function. Otherwise, we end up filling out all of
DC's link information with zeroes.
So, let's restore that and hopefully fix this DSC regression.
