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: gscps2 - fix compilation error introduced with switch to guards

2024-10-20T03:53:32+00:00

Change 44f920069911 ("Input: gscps2 - use guard notation when acquiring spinlock") introduced typos resulting in compile errors noticed by the kernel test robot. Fix them. Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202410192242.GL0CoAbv-lkp@intel.com/ Fixes: 44f920069911 ("Input: gscps2 - use guard notation when acquiring spinlock") Signed-off-by: Dmitry Torokhov

Input: gscps2 - use guard notation when acquiring spinlock

2024-10-04T07:58:16+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/20240905041732.2034348-11-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.

Input: gscps2 - check return value of ioremap() in gscps2_probe()

2022-08-02T08:31:59+00:00

The function ioremap() in gscps2_probe() can fail, so its return value should be checked. Fixes: 4bdc0d676a643 ("remove ioremap_nocache and devm_ioremap_nocache") Cc: # v5.6+ Reported-by: Hacash Robot Signed-off-by: Xie Shaowen Signed-off-by: Helge Deller

parisc: Make struct parisc_driver::remove() return void

2021-08-30T08:18:25+00:00

The caller of this function (parisc_driver_remove() in arch/parisc/kernel/drivers.c) ignores the return value, so better don't return any value at all to not wake wrong expectations in driver authors. The only function that could return a non-zero value before was ipmi_parisc_remove() which returns the return value of ipmi_si_remove_by_dev(). Make this function return void, too, as for all other callers the value is ignored, too. Also fold in a small checkpatch fix for: WARNING: Unnecessary space before function pointer arguments + void (*remove) (struct parisc_device *dev); Acked-by: Dmitry Torokhov (for drivers/input) Signed-off-by: Uwe Kleine-König Acked-by: Sudip Mukherjee Acked-by: Jiri Slaby Signed-off-by: Helge Deller
