Subject: [PATCH v3 19/19] arch/x86: Implement <asm/fb.h> with generic helpers
Date:   Mon, 17 Apr 2023 14:56:51 +0200
Message-Id: <20230417125651.25126-20-tzimmermann@suse.de>
In-Reply-To: <20230417125651.25126-1-tzimmermann@suse.de>

Precedence: bulk

Include <asm-generic/fb.h> and set the required preprocessor tokens
correctly. x86 now implements its own set of fb helpers, but still
follows the overall pattern of the other <asm/fb.h> files.

v3:
	* clarified commit message
