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: elo - switch to use scnprintf() to suppress truncation warning

Switch the driver to use scnprintf() to avoid warnings about potential truncation of "phys" field which we can tolerate. Signed-off-by: Andy Shevchenko Link: https://patch.msgid.link/20260113082856.83617-1-andriy.shevchenko@linux.intel.com Signed-off-by: Dmitry Torokhov

Input: elo - use guard notation when pausing serio port

2024-10-04T07:58:16+00:00

Using guard notation makes the code more compact and error handling more robust by ensuring that serio ports are resumed in all code paths when control leaves critical section. Link: https://lore.kernel.org/r/20240905041732.2034348-10-dmitry.torokhov@gmail.com Signed-off-by: Dmitry Torokhov

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

2024-06-09T21:38:38+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). The refactoring is mostly trivial except for "usbtouchscreen.c" file. Here, in the "mtouch_alloc" and "nexio_alloc" functions, it is necessary to use a variable with a predefined type instead of the "usbtouch->priv" variable (void * type). This way, the "sizeof" operator can now know the correct size. Moreover, we need to set the "usbtouch->priv" pointer after the memory allocation since now the "kmalloc" return value is not assigned directly. This patch has no effect on runtime behavior.
