2022-01-12video: vga16fb: Fix logic that checks for the display standardJavier Martinez Canillas1-0/+5
The vga16fb framebuffer driver supports both Enhanced Graphics Adapter (EGA) and Video Graphics Array (VGA) 16 color graphic cards. But the logic to check whether the EGA or VGA standard are used is not correct. It just checks if screen_info.orig_video_isVGA is set, but it should check if is set to VIDEO_TYPE_VGAC instead. This means that it assumes to be VGA even if is set to VIDEO_TYPE_EGAC. All non-x86 architectures though treat orig_video_isVGA as a boolean so only do the change for x86 and keep the old logic for the other arches.

2022-01-12video: vga16fb: Only probe for EGA and VGA 16 color graphic cardsJavier Martinez Canillas1-0/+24
The vga16fb framebuffer driver only supports Enhanced Graphics Adapter (EGA) and Video Graphics Array (VGA) 16 color graphic cards. But it doesn't check if the adapter is one of those or if a VGA16 mode is used. This means that the driver will be probed even if a VESA BIOS Extensions (VBE) or Graphics Output Protocol (GOP) interface is used. This issue has been present for a long time but it was only exposed by commit d391c5827107 ("drivers/firmware: move x86 Generic System Framebuffers support") since the platform device registration to match the {vesa,efi}fb drivers is done later as a consequence of that change. All non-x86 architectures though treat orig_video_isVGA as a boolean so only do the supported video mode check for x86 and not for other arches.

2021-05-07treewide: remove editor modelines and cruftMasahiro Yamada1-10/+0
The section "19) Editor modelines and other cruft" in Documentation/process/coding-style.rst clearly says, "Do not include any of these in source files." I recently receive a patch to explicitly add a new one. Let's do treewide cleanups, otherwise some people follow the existing code and attempt to upstream their favoriate editor setups. It is even nicer if scripts/checkpatch.pl can check it. If we like to impose coding style in an editor-independent manner, I think editorconfig (patch [1]) is a saner solution.

2020-09-08video: fbdev: vga16fb: fix setting of pixclock because a pass-by-value errorColin Ian King1-7/+7
The pixclock is being set locally because it is being passed as a pass-by-value argument rather than pass-by-reference, so the computed pixclock is never being set in var->pixclock. Fix this by passing by reference.

2019-12-05video: constify fb ops across all driversJani Nikula1-1/+1
Now that the fbops member of struct fb_info is const, we can start making the ops const as well. This does not cover all drivers; some actually modify the fbops struct, for example to adjust for different configurations, and others do more involved things that I'd rather not touch in practically obsolete drivers. Mostly this is the low hanging fruit where we can add "const" and be done with it. v3: - un-constify atyfb, mb862xx, nvidia and uvesabf (0day) v2: - fix typo (Christophe de Dinechin) - use "static const" instead of "const static" in mx3fb.c - also constify smscufx.c Cc: linux-fbdev@vger.kernel.org Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/ce67f14435f3af498f2e8bf35ce4be11f7504132.1575390740.git.jani.nikula@intel.com

2016-09-27video: fbdev: constify fb_fix_screeninfo and fb_var_screeninfo structuresJulia Lawall1-1/+1
These structures are only used to copy into other structures, so declare them as const. The semantic patch that makes this change in the fb_fix_screeninfo case is as follows (http://coccinelle.lip6.fr/). The fb_var_screeninfo case is analogous. // <smpl> @r disable optional_qualifier@ identifier i; position p; @@ static struct fb_fix_screeninfo i@p = { ... }; @ok@ identifier r.i; expression e; position p; @@ e = i@p @bad@ position p != {r.p,ok.p}; identifier r.i; struct fb_fix_screeninfo e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct fb_fix_screeninfo i = { ... }; // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-04-17video: move fbdev to drivers/video/fbdevTomi Valkeinen1-0/+1464
The drivers/video directory is a mess. It contains generic video related files, directories for backlight, console, linux logo, lots of fbdev device drivers, fbdev framework files. Make some order into the chaos by creating drivers/video/fbdev directory, and move all fbdev related files there. No functionality is changed, although I guess it is possible that some subtle Makefile build order related issue could be created by this patch.
