[PATCH AUTOSEL 6.10 26/34] drm/panic: depends on !VT_CONSOLE

[Sasha Levin]

From: Jocelyn Falempe <jfalempe at redhat.com>

[ Upstream commit 1ac6ac9ec069ed0cfdb1c207ae23f6c40ac57437 ]

The race condition between fbcon and drm_panic can only occurs if
VT_CONSOLE is set. So update drm_panic dependency accordingly.
This will make it easier for Linux distributions to enable drm_panic
by disabling VT_CONSOLE, and keeping fbcon terminal.
The only drawback is that fbcon won't display the boot kmsg, so it
should rely on userspace to do that.
At least plymouth already handle this case with
