* acpi-bus: ACPI: scan: Set power.no_pm for all struct acpi_device objects ACPI: bus: Eliminate struct acpi_driver * acpi-numa: ACPI: NUMA: remove redundant node_set() call * acpi-apei: ACPI: APEI: GHES: Mark ghes_in_nmi_spool_from_list() as maybe unused * pnp: PNP: Fix card device cleanup on registration failure

PNP: Fix card device cleanup on registration failure

2026-07-06T18:05:14+00:00

pnp_add_card() ignores __pnp_add_device() failures. If device_register() fails there, the device is removed from the global and protocol lists, but remains on the card list and its device reference is not dropped. Remove the failed device from the card list and call put_device() before continuing with the remaining card devices.

* pnp: PNP: Drop unused assignment of pnp_device_id driver data

Replace by more specific (c files)

2026-07-03T05:38:17+00:00

Replace the #include of by the more specific where applicable. For most cases the include can be dropped completely, only a few drivers need one or two headers added.

PNP: Drop unused assignment of pnp_device_id driver data

2026-06-30T12:35:52+00:00

The driver explicitly sets the .driver_data member of struct pnp_device_id to zero without relying on that value. Drop these unused assignments. While touching this array simplify the list terminator and align the the array's coding style to what is used most for these. This patch doesn't modify the compiled array, only its representation in source form benefits. The former was confirmed with builds on x86 and arm64.

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

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

kernel.h: drop hex.h and update all hex.h users

2026-01-21T03:44:19+00:00

Remove from and update all users/callers of hex.h interfaces to directly #include as part of the process of putting kernel.h on a diet. Removing hex.h from kernel.h means that 36K C source files don't have to pay the price of parsing hex.h for the roughly 120 C source files that need it. This change has been build-tested with allmodconfig on most ARCHes. Also, all users/callers of in the entire source tree have been updated if needed (if not already #included).

PNP: Fix ISAPNP to generate uevents to auto-load modules

2025-11-18T16:35:36+00:00

Currently ISAPNP devices do not generate an uevent for udev to auto-load the driver modules for Creative SoundBlaster or Gravis UltraSound to just work.
