tuhaowen 96e61cc6c0 PM: sleep: console: Fix the black screen issue ... [ Upstream commit 4266e8fa56 ] When the computer enters sleep status without a monitor connected, the system switches the console to the virtual terminal tty63(SUSPEND_CONSOLE). If a monitor is subsequently connected before waking up, the system skips the required VT restoration process during wake-up, leaving the console on tty63 instead of switching back to tty1. To fix this issue, a global flag vt_switch_done is introduced to record whether the system has successfully switched to the suspend console via vt_move_to_console() during suspend. If the switch was completed, vt_switch_done is set to 1. Later during resume, this flag is checked to ensure that the original console is restored properly by calling vt_move_to_console(orig_fgconsole, 0). This prevents scenarios where the resume logic skips console restoration due to incorrect detection of the console state, especially when a monitor is reconnected before waking up.
