drivers/gpu/drm/drm_dp_mst_topology.c: In function __topology_ref_save:
drivers/gpu/drm/drm_dp_mst_topology.c:1424:6: error: implicit declaration of function stack_trace_save; did you mean stack_depot_save? [-Werror=implicit-function-declaration]
  n = stack_trace_save(stack_entries, ARRAY_SIZE(stack_entries), 1);
      ^~~~~~~~~~~~~~~~
      stack_depot_save
drivers/gpu/drm/drm_dp_mst_topology.c: In function __dump_topology_ref_history:
drivers/gpu/drm/drm_dp_mst_topology.c:1513:3: error: implicit declaration of function stack_trace_snprint; did you mean acpi_trace_point? [-Werror=implicit-function-declaration]
   stack_trace_snprint(buf, PAGE_SIZE, entries, nr_entries, 4);
   ^~~~~~~~~~~~~~~~~~~
   acpi_trace_point

stack_trace_save and stack_trace_snprint are declared in <linux/stacktrace.h>,
so there is need to include it, and <linux/stackdepot.h> is already included
by practices, so just replace <linux/stackdepot.h> by <linux/stacktrace.h>.
