Subject: [PATCH 2/8] firmware: efi: Never declare sysfb_primary_display on x86
Date: Thu,  2 Apr 2026 11:09:16 +0200	[thread overview]
Message-ID: <20260402092305.208728-3-tzimmermann@suse.de> (raw)
In-Reply-To: <20260402092305.208728-1-tzimmermann@suse.de>

The x86 architecture comes with its own instance of the global
state variable sysfb_primary_display. Never declare it in the EFI
subsystem. Fix the test for CONFIG_FIRMWARE_EDID accordingly.

Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de>
Fixes: e65ca1646311 ("efi: export sysfb_primary_display for EDID")
