drm/panel: find_panel_by_fwnode() return a counted reference
...
find_panel_by_fwnode() is the fwnode-based counterpart to
of_drm_find_panel(), used internally by drm_panel_add_follower().
Like of_drm_find_panel(), it returned an unrefcounted pointer,
leaving a window where the panel could be freed between the lookup
and first use.
drm_panel_add_follower() worked around the missing panel kref by
calling get_device() on the panel's underlying struct device.
However, get_device() only prevents the device kobject from being freed.
It does not prevent the panel's kzalloc()'d container memory from being
released when the kref reaches zero.
Apply the same fix: call drm_panel_get() under panel_lock before
returning. Since find_panel_by_fwnode() now transfers a counted
reference to drm_panel_add_follower(), drm_panel_remove_follower()
must balance it with a matching drm_panel_put().

drm/panel: of_drm_find_panel() return a counted reference
...
Callers of of_drm_find_panel() and drm_of_find_panel_or_bridge()
receive a pointer with no reference held, creating a window where
the panel device can be unregistered and freed between the lookup
and first use (e.g., drm_panel_prepare()).
Fix the lookup function by acquiring a reference with drm_panel_get()
before returning, under panel_lock. Callers are now responsible for
calling drm_panel_put() when they no longer need the pointer.
For bridge drivers that immediately wrap the panel in a panel_bridge
(which acquires its own reference), release the lookup reference right
after the bridge creation call.
For analogix-anx6345, which stores the panel for direct use, release
the reference in the i2c remove path.
For platform drivers using analogix_dp_core with a component lifecycle
(exynos_dp, rockchip analogix_dp), release the lookup reference in the
platform remove() function. The panel_bridge created during bind() holds
a separate reference that devm cleanup releases after remove() returns.
Also fix devm_drm_of_get_bridge() and drmm_of_get_bridge() in
bridge/panel.c itself, update a second batch of drivers calling
of_drm_find_panel() or drm_of_find_panel_or_bridge() to release the
lookup reference after wrapping the panel in a bridge, and handle the
cases where a panel is found but cannot be used, dropping the reference
immediately in those paths.

drm/panel: have drm_panel_add/remove manage a list reference
...
The global panel_list holds raw pointers to drm_panel objects.
Nothing prevents a panel from being freed while it is still linked
in the list: if a driver's probe calls drm_panel_add() and then
fails at a later step, panel->list remains in panel_list. Any
subsequent call to of_drm_find_panel() that iterates the list will
dereference freed memory.
Have drm_panel_add() acquire a reference via drm_panel_get() before
inserting the panel into the list, and have drm_panel_remove() drop
it via drm_panel_put() after removing the panel from the list. The
global registry now holds a counted reference for as long as the
panel is listed, ensuring the object outlives any concurrent lookup.

drm/v3d: Associate BOs with every job that accesses them
...
A submission can expand into a chain of jobs (e.g. bin + render + cache
clean). Implicit synchronization in v3d_submit_lock_reservations() is gated
on each job's bo[], but the BO list was only ever attached to the last job
of the chain. When that last job is a trailing CACHE_CLEAN job, the job
that actually consumes the BOs (that is, a RENDER or CSD job) was left with
bo_count == 0 and picked up no implicit dependencies. It could therefore
be dispatched to the hardware and read a BO while another context was still
writing it, leading to data corruption.
Attach the BOs to the job that consumes them, so (1) it acquires the
correct implicit dependencies during reservation locking and (2) they are
kept mapped until the end of the submission. Give it references to all
consuming job's BOs through v3d_job_reference_bos() instead of looking the
handles up a second time; that avoids a redundant lookup and guarantees
both jobs reference the exact same objects.
As the CACHE_CLEAN job now carries a BO array as well, add a per-job
`has_implicit_dep` flag so that only the consuming jobs take implicit
dependencies. The CACHE_CLEAN job (a global flush) and the BIN job (binning
waiting on another context is not a realistic scenario) are excluded.

gpu: host1x: Change pin_job() return type to int
...
pin_job() returns negative errno values on error paths (-EINVAL,
-ENOMEM, PTR_ERR() of mapping) but was declared as unsigned int.
The caller would immediately cast back to int, so there was no
functional issue, but it still warrants fixing.

gpu: host1x: Avoid stack over-read in debug output helpers
...
host1x_debug_output() and host1x_debug_cont() used vsnprintf(), which
returns the length the formatted string would have reached with an
unbounded buffer. That return value was passed straight to o->fn as
the number of bytes to emit.
This could cause a read past end of the output buffer if a call to
host1x_debug_* produced a string longer than 256 bytes. This only
affected the debugfs files as the printk debug sink ignores the
number of bytes. In practice, this is very unlikely to occur.
Fix by switching to vscnprintf(), which returns the number of bytes
actually written.

gpu: host1x: Fix offset calculation in trace_write_gather
...
When a gather longer than 2*TRACE_MAX_LENGTH (256) words is traced
through host1x_cdma_push_gather, the reported BO offset drifts from
the third iteration onward.
Fix the calculation by properly calculating the value on each loop
rather than accumulating.
In reality, gathers tend to be pretty short so this is unlikely to
ever have been observed.

gpu: host1x: Avoid double device_add when clients already present
...
host1x_device_add looks through the idle clients list to populate
subdevs, and any matches entries are moved from the subdevs list
to the active list. If all subdevs are populated, device_add will
be called on the device. The secondary "subdevs list empty" check
will then incorrectly again call device_add.
However, this would require a convoluted scenario since clients don't
typically end up on the idle clients list.
Fix by checking whether the device was already added before adding
again.

gpu: host1x: Wait for timeout worker completion on channel free
...
cdma_timeout_destroy() used cancel_delayed_work() to cancel pending
timeout work when destroying the CDMA. Usually this is fine, but
there is a narrow race condition where the timeout handler has started
execution but has not taken cdma->lock; the channel is freed causing
cdma_stop to take cdma->lock and flush the channel; host1x_cdma_deinit
then proceeds with deinitializing cdma while the handler is waiting to
take cdma->lock.
Therefore change cdma_timeout_destroy to use cancel_delayed_work_sync
instead to ensure any pending timeout work completes before proceeding.

drm/bridge: tc358767: clamp the reported AUX read size to the request
...
tc_aux_transfer() clamps an AUX read to the payload limit:
size_t size = min_t(size_t, DP_AUX_MAX_PAYLOAD_BYTES - 1, msg->size);
After the transfer it replaces size with the byte count the controller
reports in AUX_BYTES:
if (size)
size = FIELD_GET(AUX_BYTES, auxstatus);
AUX_BYTES is GENMASK(15, 8), so it can be up to 255. Nothing clamps it
back to the request. tc_aux_read_data() reads that many bytes into the
16-byte auxrdata stack buffer, then copies them into the caller buffer. A
reported count of 255 makes the read run to 256 bytes and overruns both.
The controller should never report more than it was asked to transfer, so
this is defense in depth rather than a live hole. The reported count is
only lightly trusted, and the check is cheap. Clamp it back to the request,
the same way ti-sn65dsi86 does in commit aca58eac5212dfe7c4d9https://patch.msgid.link/20260701064440.1541418-1-maoyixie.tju@gmail.com

drm/bridge: Remove legacy bridge callback support
...
All bridge drivers have been converted to the atomic variants of the
enable, disable, pre_enable, and post_disable callbacks.
Remove the deprecated legacy hooks from drm_bridge_funcs, the
drm_bridge_is_atomic() helper that was only needed to distinguish
between atomic and non-atomic bridges, and the legacy bridge test
cases.
Since all bridges are now atomic, unconditionally initialize the
private object state at attach time.
