Subject: [PATCH 01/12] efi: Do not include <linux/screen_info.h> from EFI header
Date:   Thu, 29 Jun 2023 13:45:40 +0200
Message-ID: <20230629121952.10559-2-tzimmermann@suse.de>
In-Reply-To: <20230629121952.10559-1-tzimmermann@suse.de>
References: <20230629121952.10559-1-tzimmermann@suse.de>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

The header file <linux/efi.h> does not need anything from
<linux/screen_info.h>. Declare struct screen_info and remove
the include statements. Update a number of source files that
require struct screen_info's definition.
