ACPICA: Dispatcher: Remove unnecessary call to debugger
ACPICA commit eaa455accf165fee2df26410e271aab162264f6c
UBSAN reports an index out of range use in dsutils.c.
acpi_db_display_argument_object(
walk_state->operands[walk_state->num_operands - 1],
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
walk_state);
This call was simply wrong, generated redundant debugger messages, and
resulted in a -1 index into the operand stack. Linux kernel bug #120351
(link #1) and #194845 (link #2).
Originally fixed by Navin P.S. (link #1, comment 8), refined by Lv Zheng
(link #3).
