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

2026-02-21T09:02:28Z

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

Input: synaptics-rmi4 - add includes for types used in rmi_2d_sensor.h

Input: include export.h in modules using EXPORT_SYMBOL*()

2025-08-21T19:00:59Z

A number of modules in the input subsystem use EXPORT_SYMBOL() and friends without explicitly including the corresponding header . While the build currently succeeds due to this header being pulled in transitively, this is not guaranteed to be the case in the future. Let's add the explicit include to make the dependencies clear and prevent future build breakage. Signed-off-by: Dmitry Torokhov

Input: synaptics-rmi4 - add support for Forcepads (F21)

Forcepad devices do not have physical buttons underneath the surface and use F21 to report "clicks" based on touch pressure. Signed-off-by: Marge Yang Link: https://lore.kernel.org/r/20250716033648.1785509-1-marge.yang@tw.synaptics.com Signed-off-by: Dmitry Torokhov

Input: synaptics-rmi - fix crash with unsupported versions of F34

2025-05-19T18:58:36Z

Sysfs interface for updating firmware for RMI devices is available even when F34 probe fails. The code checks for presence of F34 "container" pointer and then tries to use the function data attached to the sub-device. F34 assigns the function data early, before it knows if probe will succeed, leaving behind a stale pointer. Fix this by expanding checks to not only test for presence of F34 "container" but also check if there is driver data assigned to the sub-device, and call dev_set_drvdata() only after we are certain that probe is successful. This is not a complete fix, since F34 will be freed during firmware update, so there is still a race when fetching and accessing this pointer. This race will be addressed in follow-up changes.

Input: drop vb2_ops_wait_prepare/finish

2025-02-04T14:12:34Z

Since commit 88785982a19d ("media: vb2: use lock if wait_prepare/finish are NULL") it is no longer needed to set the wait_prepare/finish vb2_ops callbacks as long as the lock field in vb2_queue is set. Since the vb2_ops_wait_prepare/finish callbacks already rely on that field, we can safely drop these callbacks. This simplifies the code and this is a step towards the goal of deleting these callbacks.
