Convert 'alloc_obj' family to use the new default GFP_KERNEL argument

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: omapfb: remove duplicate check in omapfb_setup_mem()

We know "size" is non-zero because it is checked on the line before. Delete the duplicate check and pull the code in a tab. Signed-off-by: Dan Carpenter Reviewed-by: Thomas Zimmermann Signed-off-by: Helge Deller

fbdev: Switch back to struct platform_driver::remove()

2024-10-08T19:47:18Z

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/video/fbdev to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. While touching these files, make indention of the struct initializer consistent in several files. Signed-off-by: Uwe Kleine-König Reviewed-by: Thomas Zimmermann Signed-off-by: Helge Deller

fbdev: omapfb: Use sysfs_emit_at() to simplify code

2024-08-30T16:42:38Z

This file already uses sysfs_emit(). So be consistent and also use sysfs_emit_at(). Moreover, size is always < PAGE_SIZE because scnprintf() (and now sysfs_emit_at()) returns the number of characters written not including the trailing '\0'. So some tests can be removed. This slightly simplifies the code and makes it more readable. Signed-off-by: Christophe JAILLET Reviewed-by: Andi Shyti Signed-off-by: Helge Deller

fbdev: Push pgprot_decrypted() into mmap implementations

2023-11-29T11:20:44Z

If a driver sets struct fb_ops.fb_mmap, the fbdev core automatically calls pgprot_decrypted(). But the default fb_mmap code doesn't handle pgprot_decrypted(). Move the call to pgprot_decrypted() into each drivers' fb_mmap function. This only concerns fb_mmap functions for system and DMA memory. For I/O memory, which is the default case, nothing changes. The fb_mmap for I/O-memory can later be moved into a helper as well. DRM's fbdev emulation handles pgprot_decrypted() internally via the Prime helpers. Fbdev doesn't have to do anything in this case. In cases where DRM uses deferred I/O, this patch updates fb_mmap correctly.
