3bb403bf42 drm: Stop using linedur_ns and pixeldur_ns for vblank timestamps
linedur_ns, and especially pixeldur_ns are becoming rather inaccurate
to be used for the vblank timestamp correction. With 4k@60 the pixel
duration is already below 2ns, so the amount of error due to the
truncation to nanoseconds is introducing quite a bit of error.

We can avoid such problems if we instead calculate the timestamp
delta_ns directly from the dislay timings, avoiding the use of
these intermediate truncated values.

    drm: Check locking in drm_for_each_connector

I added locking checks to drm_for_each_connector but failed that
through drm_helper_connector_dpms -> drm_helper_choose_encoder_dpms
it's used in a few more places in the amdgpu resume/suspend code.

Fix them up.

Note that we could use the connector iterator macros in there too, but
that's for the future.

5c3422b0b1 drm/amdgpu: sync ce and me with SWITCH_BUFFER(2)
we used to adopt wait_reg_mem to let CE wait before DE finish page
updating, but from Tonga+, CE doesn't support wait_reg_mem package so
this logic no longer works.

so here is another approach to do same thing:
Insert two of SWITCH_BUFFER at both front and end of vm_flush can
guarantee that CE not go further to process IB_const before vm_flush
done.

Insert two of SWITCH_BUFFER also works on CI, so remove legency method
to sync CE and ME

v2:
Insert double SWITCH_BUFFER at front of vm flush as well.

1d263474c4 drm/amdgpu: unwind properly in amdgpu_cs_parser_init()
The amdgpu_cs_parser_init() function doesn't clean up after itself but
instead the caller uses a free everything function amdgpu_cs_parser_fini()
on failure.  This style of error handling is often buggy.  In this
example, we call "drm_free_large(parser->chunks[i].kdata);" when it is
an unintialized pointer or when "parser->chunks" is NULL.

I fixed this bug by adding unwind code so that it frees everything that
it allocates.

I also mode some other very minor changes:
1) Renamed "r" to "ret".
2) Moved the chunk_array allocation to the start of the function.
3) Removed some initializers which are no longer needed.
