Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00Z

This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

fbdev/mmp/mmpfb: Do not display boot-up logo

2023-09-11T13:12:31Z

The fbcon module takes care of displaying the logo, if any. Remove the code form mmpfb. It is probably no tworking as expected, as it interferes with the framebuffer console. If we want to display the logo without fbcon, we should implement this in the fbdev core code. v2: * add a note on fbcon interference (Javier) Signed-off-by: Thomas Zimmermann Acked-by: Javier Martinez Canillas Link: https://patchwork.freedesktop.org/patch/msgid/20230907085408.9354-3-tzimmermann@suse.de

fbdev/mmpfb: Use fbdev I/O helpers

2023-08-04T13:54:36Z

Set struct fb_ops and with FB_DEFAULT_IOMEM_OPS, fbdev's initializer for I/O memory. Sets the callbacks to the cfb_ and fb_io_ functions. Select the correct modules with Kconfig's FB_IOMEM_HELPERS token. The macro and token set the currently selected values, so there is no functional change. v3: * use _IOMEM_ in commit message v2: * updated to use _IOMEM_ tokens Signed-off-by: Thomas Zimmermann Reviewed-by: Sam Ravnborg Acked-by: Helge Deller Link: https://patchwork.freedesktop.org/patch/msgid/20230803184034.6456-26-tzimmermann@suse.de

fbdev: Remove FBINFO_DEFAULT from framebuffer_alloc()'ed structs

2023-07-24T14:50:38Z

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.

video: constify fb ops across all drivers

2019-12-05T08:57:53Z

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
