This commit removes an unnecessary NULL check in the
`dcn10_set_input_transfer_func` function in the `dcn10_hwseq.c` file.
The variable `tf` is assigned the address of
`plane_state->in_transfer_func` unconditionally, so it can never be
`NULL`. Therefore, the check `if (tf == NULL)` is unnecessary and has
been removed.

Fixes the below smatch warning:

The retry loop for SRIOV reset have refcount and memory leak issue.
Depending on which function call fails it can potentially call
amdgpu_amdkfd_pre/post_reset different number of times and causes
kfd_locked count to be wrong. This will block all future attempts at
opening /dev/kfd. The retry loop also leakes resources by calling
amdgpu_virt_init_data_exchange multiple times without calling the
corresponding fini function.

Align with the bare-metal reset path which doesn't have these issues.
This means taking the amdgpu_amdkfd_pre/post_reset functions out of the
reset loop and calling amdgpu_device_pre_asic_reset each retry which
properly free the resources from previous try by calling
amdgpu_virt_fini_data_exchange.

Some times a hang GPU causes multiple reset sources to schedule resets.
The second source will be able to trigger an unnecessary reset if they
schedule after we call amdgpu_device_stop_pending_resets.

Move amdgpu_device_stop_pending_resets to after the reset is done. Since
at this point the GPU is supposedly in a good state, any reset scheduled
after this point would be a legitimate reset.

Remove unnecessary and incorrect checks for amdgpu_in_reset that was
kinda serving this purpose.

When building with clang 19 or newer (which strengthened some of the
enum conversion warnings for C), there is a warning (or error with
CONFIG_WERROR=y) around doing arithmetic with an enumerated type and a
floating point expression.

  drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/dml21/src/dml2_dpmm/dml2_dpmm_dcn4.c:181:58: error: arithmetic between enumeration type 'enum dentist_divider_range' and floating-point type 'double' [-Werror,-Wenum-float-conversion]

        |                                  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~
  1 error generated.

This conversion is expected due to the nature of the enumerated value
and definition, so silence the warning by casting the enumeration to an
integer explicitly to make it clear to the compiler.

This 8.4 inch panel is integrated in the Ayaneo Kun handheld
device. The panel resolution is 2560×1600, i.e. it has
portrait dimensions.

Decoding the EDID shows:
Manufacturer: MSF
Model: 4099
Display Product Name: 'TV080WUM-NL0 '

Judging from the product name this might be a clone of a
BOE panel, but with larger dimensions.

Panel frequently shows non-functional backlight control. Adding
some debug prints to update_connector_ext_caps() shows that
something the OLED bit of ext_caps is set, and then the driver
assumes that backlight is controlled via AUX.

Forcing backlight control to PWM via amdgpu.backlight=0 restores
backlight operation.

There is a race condition when re-creating a kfd_process for a process.
This has been observed when a process under the debugger executes
exec(3).  In this scenario:
- The process executes exec.
 - This will eventually release the process's mm, which will cause the
   kfd_process object associated with the process to be freed
   (kfd_process_free_notifier decrements the reference count to the
   kfd_process to 0).  This causes kfd_process_ref_release to enqueue
   kfd_process_wq_release to the kfd_process_wq.
- The debugger receives the PTRACE_EVENT_EXEC notification, and tries to
  re-enable AMDGPU traps (KFD_IOC_DBG_TRAP_ENABLE).
 - When handling this request, KFD tries to re-create a kfd_process.
   This eventually calls kfd_create_process and kobject_init_and_add.

At this point the call to kobject_init_and_add can fail because the
old kfd_process.kobj has not been freed yet by kfd_process_wq_release.

This patch proposes to avoid this race by making sure to drain
kfd_process_wq before creating a new kfd_process object.  This way, we
know that any cleanup task is done executing when we reach
kobject_init_and_add.
