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

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

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

rapidio: remove unused functions

2025-05-12T00:54:09+00:00

rio_request_dma() and rio_dma_prep_slave_sg() were added in 2012 by commit e42d98ebe7d7 ("rapidio: add DMA engine support for RIO data transfers") but never used. rio_find_mport() last use was removed in 2013 by commit 9edbc30b434f ("rapidio: update enumerator registration mechanism") rio_unregister_scan() was added in 2013 by commit a11650e11093 ("rapidio: make enumeration/discovery configurable") but never used. Remove them. Link: https://lkml.kernel.org/r/20250419203012.429787-3-linux@treblig.org Signed-off-by: Dr. David Alan Gilbert Cc: Alexandre Bounine Cc: Matt Porter Signed-off-by: Andrew Morton

rapidio: rio: fix possible name leak in rio_register_mport()

2022-12-01T00:13:17+00:00

If device_register() returns error, the name allocated by dev_set_name() need be freed. It should use put_device() to give up the reference in the error path, so that the name can be freed in kobject_cleanup(), and list_del() is called to delete the port from rio_mports.

rapidio: remove unused rio_get_asm() and rio_get_device()

2020-12-16T06:46:18+00:00

The functions rio_get_asm() and rio_get_device() are globally exported but have almost no users in tree. The only user is rio_init_mports() which invokes it via rio_init(). rio_init() iterates over every registered device and invokes rio_fixup_device(). It looks like a fixup function which should perform a "change" to the device but does nothing. It has been like this since its introduction in commit 394b701ce4fbf ("[PATCH] RapidIO support: core base") which was merged into v2.6.15-rc1. Remove rio_init() because the performed fixup function (rio_fixup_device()) does nothing. Remove rio_get_asm() and rio_get_device() which have no callers now.

The local variable "rc" will be set to an appropriate value a bit later. Thus omit the explicit initialisation at the beginning.
