This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

Ensure that the DAC output is enabled at the correct time by
moving it to the DCE link encoder similarly to how digital
outputs are enabled.
This also removes the call to DAC1EncoderControl from the DCE
HWSS, which always felt like it was a hacky solution.

User may connect mst dock with multi monitors and do quick unplug
and plug in one of the monitor. This operatioin may create CSN from
dock to display driver. Then display driver would disable and then enable
mst link and also disable/enable DPCD mst_en bit in dock RX. However,
when mst_en bit being disabled, if dock has another CSN message to
transmit then the message would be removed because of the disabling of
mst_en. In this case, the message is missing and it ends up no display in
the replugged monitor.
[HOW]
Don't disable mst_en bit when link still has sink connected.

edp_pr_get_state() incorrectly casts a uint64_t * to uint32_t * when
calling dc_wake_and_execute_gpint(). The GPINT path writes only 32 bits,
leaving the upper 32 bits of the u64 output uninitialized. Replace the
cast with a u32 temporary and copy the result into the u64 pointer.
Fixes the below:
drivers/gpu/drm/amd/amdgpu/../display/dc/link/protocols/link_edp_panel_control.c
1448 bool edp_pr_get_state(const struct dc_link *link, uint64_t *state)
^^^^^^^^^^^^^^^
1449 {
...
1457 do {
1458 // Send gpint command and wait for ack
--> 1459 if (!dc_wake_and_execute_gpint(dc->ctx, DMUB_GPINT__GET_REPLAY_STATE, panel_inst,
1460 (uint32_t *)state, DM_DMUB_WAIT_TYPE_WAIT_WITH_REPLY)) {
^^^^^^^^^^^^^^^^^
The dc_wake_and_execute_gpint() function doesn't take a u64, it takes a
u32. It tries to initialize the state to zero at the start but that's
not going to work because of the type mismatch. It suggests that
callers are allowed to pass uninitialized data to edp_pr_get_state() but
at present there are no callers so this is only a bug in the code but
doesn't affect runtime.
1461 // Return invalid state when GPINT times out
1462 *state = PR_STATE_INVALID;
1463 }
