Randy Dunlap e28b030aec efi: sysfb_efi: fix W=1 warnings when EFI is not set [ Upstream commit `19fdc68aa7` ] A build with W=1 fails because there are code and data that are not needed or used when CONFIG_EFI is not set. Move the "#ifdef CONFIG_EFI" block to earlier in the source file so that the unused code/data are not built. drivers/firmware/efi/sysfb_efi.c:345:39: warning: ‘efifb_fwnode_ops’ defined but not used [-Wunused-const-variable=] 345 \| static const struct fwnode_operations efifb_fwnode_ops = { \| ^~~~~~~~~~~~~~~~ drivers/firmware/efi/sysfb_efi.c:238:35: warning: ‘efifb_dmi_swap_width_height’ defined but not used [-Wunused-const-variable=] 238 \| static const struct dmi_system_id efifb_dmi_swap_width_height[] __initconst = { \| ^~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/firmware/efi/sysfb_efi.c:188:35: warning: ‘efifb_dmi_system_table’ defined but not used [-Wunused-const-variable=] 188 \| static const struct dmi_system_id efifb_dmi_system_table[] __initconst = { \| ^~~~~~~~~~~~~~~~~~~~~~ Fixes: `15d27b15de` ("efi: sysfb_efi: fix build when EFI is not set") Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202501071933.20nlmJJt-lkp@intel.com/ Cc: David Rheinsberg <david@readahead.eu> Cc: Hans de Goede <hdegoede@redhat.com> Cc: Javier Martinez Canillas <javierm@redhat.com> Cc: Peter Jones <pjones@redhat.com> Cc: Simona Vetter <simona@ffwll.ch> Cc: linux-fbdev@vger.kernel.org Cc: Ard Biesheuvel <ardb@kernel.org> Cc: linux-efi@vger.kernel.org Reviewed-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Signed-off-by: Sasha Levin <sashal@kernel.org>		History 2025-02-21 13:49:17 +01:00

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
