misc: Use named initializers for arrays of spi_device_data

2026-07-31T12:20:50+00:00

While being less compact, using named initializers allows to more easily see which members of the structs are assigned which value without having to lookup the declaration of the struct. And it's also more robust against changes to the struct definition. The mentioned robustness is relevant for a planned change to struct spi_device_id that replaces .driver_data by an anonymous union. While touching all these arrays, unify usage of whitespace. This patch doesn't modify the compiled arrays, only their representation in source form benefits.

misc: keba: cp500: use pcim_enable_device()

2026-07-17T13:50:34+00:00

Switch from pci_enable_device() to pcim_enable_device() so the PCI device is automatically disabled on probe error and driver removal. Drop the now redundant manual pci_disable_device() and pci_clear_master() calls, since pcim's release path clears bus mastering and disables the device.

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

misc: keba: Fix kernfs warning on module unload

2025-01-10T09:16:39+00:00

Unloading the cp500 module leads to the following warning: kernfs: can not remove 'eeprom', no directory WARNING: CPU: 1 PID: 1610 at fs/kernfs/dir.c:1683 kernfs_remove_by_name_ns+0xb1/0xc0 The parent I2C device of the nvmem devices is freed before the nvmem devices. The reference to the nvmem devices is put by devm after cp500_remove(), but at this time the parent I2C device does not exist anymore as the I2C controller and its devices have already been freed in cp500_remove(). Thus, nvmem tries to remove an entry from an already deleted directory. Free nvmem devices before I2C controller auxiliary device.
