Subject: fbdev: use panic_in_progress() helper
Date: Mon, 25 Aug 2025 10:29:30 +0800
Update the fbcon_skip_panic() function to use the panic_in_progress()
helper.
The previous direct access to panic_cpu is less readable and is being
replaced by a dedicated function that more clearly expresses the intent.
This change is part of a series to refactor the kernel's panic handling
logic for better clarity and robustness.
