From dbc54475c142215a8b85667b7ec2791cc06eb377 Mon Sep 17 00:00:00 2001 From: Mitchell Horne Date: Tue, 13 Apr 2021 14:34:58 -0300 Subject: arm64: adjust comments in dbg_monitor_exit() These comments were copied from dbg_monitor_enter(), but the intended modifications weren't made. Update them to reflect what this code actually does.
