fbdev: Remove FBINFO_DEFAULT from framebuffer_alloc()'ed structs

2023-07-24T14:50:38+00:00

The flag FBINFO_DEFAULT is 0 and has no effect, as struct fbinfo.flags has been allocated to zero by framebuffer_alloc(). So do not set it. Flags should signal differences from the default values. After cleaning up all occurrences of FBINFO_DEFAULT, the token will be removed. v4: * clarify commit message (Geert, Dan) v2: * fix commit message (Miguel) Signed-off-by: Thomas Zimmermann Acked-by: Sam Ravnborg Cc: Helge Deller Cc: Nicolas Ferre Cc: Benjamin Herrenschmidt Cc: Ferenc Bakonyi Cc: "K.

fbdev: clps711x-fb: Convert to platform remove callback returning void

2023-04-24T09:48:29+00:00

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by: Uwe Kleine-König Signed-off-by: Helge Deller

fbdev: clps711x-fb: Use devm_platform_get_and_ioremap_resource()

2023-03-14T17:49:39+00:00

According to commit 890cc39a8799 ("drivers: provide devm_platform_get_and_ioremap_resource()"), convert platform_get_resource(), devm_ioremap_resource() to a single call to devm_platform_get_and_ioremap_resource(), as this is exactly what this function does.

fbdev/clps711x-fb: Do not set struct fb_info.apertures

2023-01-13T11:54:25+00:00

Generic fbdev drivers use the apertures field in struct fb_info to control ownership of the framebuffer memory and graphics device. Do not set the values in clps711x-fb.

fbdev: Move fbdev drivers from strlcpy to strscpy

Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script.

Since version 5.13, the standard syscon bindings have been added to all clps711x DT nodes, so we can now use the more general syscon_regmap_lookup_by_phandle function to get the syscon pointer. Signed-off-by: Alexander Shiyan Signed-off-by: Helge Deller

video: constify fb ops across all drivers

2019-12-05T08:57:53+00:00

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 Signed-off-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/ce67f14435f3af498f2e8bf35ce4be11f7504132.1575390740.git.jani.nikula@intel.com
