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

parisc: kernel: replace kfree() with put_device() in create_tree_node()

2026-02-06T23:45:18Z

If device_register() fails, put_device() is the correct way to drop the device reference. Found by code review. Fixes: 1070c9655b90 ("[PA-RISC] Fix must_check warnings in drivers.c") Cc: stable@vger.kernel.org Signed-off-by: Haoxiang Li Signed-off-by: Helge Deller

parisc: Fix iodc and device path return values on old machines

2025-10-09T21:45:04Z

Older machines may not fully initialize the return values when asking for IODC and device path data when building the inventory. Work around possible firmware leaks by proper initialization of the variables. Signed-off-by: Helge Deller

driver core: have match() callback in struct bus_type take a const *

2024-07-03T13:16:54Z

In the match() callback, the struct device_driver * should not be changed, so change the function callback to be a const *. This is one step of many towards making the driver core safe to have struct device_driver in read-only memory. Because the match() callback is in all busses, all busses are modified to handle this properly. This does entail switching some container_of() calls to container_of_const() to properly handle the constant *. For some busses, like PCI and USB and HV, the const * is cast away in the match callback as those busses do want to modify those structures at this point in time (they have a local lock in the driver structure.) That will have to be changed in the future if they wish to have their struct device * in read-only-memory. Cc: Rafael J.

parisc: make parisc_bus_type const

2024-02-27T21:51:44Z

Since commit d492cc2573a0 ("driver core: device.h: make struct bus_type a const *"), the driver core can properly handle constant struct bus_type, move the parisc_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
