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

This was done entirely with mindless brute force, using git grep -l '\

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

Input: sa1111ps2 - use guard notation when acquiring spinlock

2024-10-04T07:58:17+00:00

Using guard notation makes the code more compact and error handling more robust by ensuring that locks are released in all code paths when control leaves critical section. Link: https://lore.kernel.org/r/20240905041732.2034348-18-dmitry.torokhov@gmail.com Signed-off-by: Dmitry Torokhov

Input: serio - use sizeof(*pointer) instead of sizeof(type)

2024-06-07T18:59:21+00:00

It is preferred to use sizeof(*pointer) instead of sizeof(type) due to the type of the variable can change and one needs not change the former (unlike the latter). This patch has no effect on runtime behavior.

Input: move from strlcpy with unused retval to strscpy

2022-08-18T22:44:08+00:00

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.

ARM: 9048/1: sa1111: make sa1111 bus's remove callback return void

2021-02-01T19:42:13+00:00

The driver core ignores the return value of struct device_driver::remove because there is only little that can be done. To simplify the quest to make this function return void, let struct sa1111_driver::remove return void, too. All users already unconditionally return 0, this commit makes it obvious that returning an error code is a bad idea and ensures future users behave accordingly.

Input: sa1111ps2 - extend test delay

2017-09-26T18:52:08+00:00

A 2us delay is too small for the bus to settle after writing to the register. Extend to 10us which gives more reliable results. Signed-off-by: Russell King Signed-off-by: Dmitry Torokhov
