misc: pch_phub: Make MAC address configuration more robust

2026-07-17T13:49:01+00:00

The comment in pch_phub_write_gbe_mac_addr() suggests that only EG20T, ML7831 and ML7223 are handled. Replace the code construct using an if with a switch that has the same semantics but issues a warning if a new device type is added to the driver without adapting this function.

misc: pch_phub: Drop unused members from struct pch_phub_reg

2026-07-17T13:49:01+00:00

Since commit d14b649fd99f ("misc: pch_phub: Drop two unused functions") all the register values in struct pch_phub_reg are unused. Drop them.

misc: pch_phub: Complete enum usage for device identification

2026-07-17T13:49:01+00:00

Recently an enum was introduced to identify the different hardware variants instead of magic constants. The respective commit however missed to adapt one code location that still checks the old values. As the values shifted by one this is a relevant fix.

misc: pch_phub: Introduce an enum for device indentification

2026-05-23T11:47:34+00:00

Instead of using magic constants give them names that make the code more idiomatic. While touching the pci_device_id array, use named initializers to assign .driver_data.

misc: pch_phub: Drop two unused functions

2026-05-23T11:47:34+00:00

The two functions are unused since commit 34afa1d657d4 ("misc/pch_phub.c: use generic power management") but the compiler didn't warn about it because the same commit marked the functions as __maybe_unsed.

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).

sysfs: treewide: switch back to bin_attribute::read()/write()

2025-06-17T08:44:13+00:00

The bin_attribute argument of bin_attribute::read() is now const. This makes the _new() callbacks unnecessary. Switch all users back.

misc: pch_phub: Constify 'struct bin_attribute'

2024-12-24T08:36:02+00:00

The sysfs core now allows instances of 'struct bin_attribute' to be moved into read-only memory. Make use of that to protect them against accidental or malicious modifications.
