net: pse-pd: set user byte command SUB2 field

2026-06-17T22:57:16+00:00

The Set User Byte to Save command has three subject bytes. The PD692x0 protocol guides defines SUB2 with value 0x4e, while SUB1 carries the NVM user byte. Template only initialized SUB and SUB1. Fill SUB2 explicitly so the command matches the documented layout.

net: pse-pd: pd692x0: support disabling disable ports GPIO

2026-06-10T01:52:03+00:00

Microchip PSE controllers have a dedicated disable ports input that like it name says disables PoE on all ports. So lets support parsing that GPIO and using the GPIO flags to set it low by default and enable PoE on all ports during probe.

net: pse-pd: Use named initializers for arrays of i2c_device_data

2026-05-21T02:01:48+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 i2c_device_id that replaces .driver_data by an anonymous union. While touching all these arrays, unify usage of whitespace in the list terminator. This patch doesn't modify the compiled arrays, only their representation in source form benefits. The former was confirmed with x86 and arm64 builds.

net: pse-pd: fix sign on -ENOENT check in of_load_pse_pis()

2026-05-20T00:44:27+00:00

of_count_phandle_with_args() returns the count on success and a negative errno on failure, including -ENOENT when the "pairsets" property is absent. The existing comparison in of_load_pse_pis() checks against ENOENT (positive 2) instead of -ENOENT, so the branch is taken for any error return: legitimate DTs that omit "pairsets" trigger a spurious "wrong number of pairsets" error and probe fails with -EINVAL. Compare against -ENOENT so a missing "pairsets" property is correctly treated as "this PI has no pairsets, continue".

net: pse-pd: fix out-of-bounds bitmap access in pse_isr() on 32-bit

2026-04-17T02:25:32+00:00

In pse_isr(), notifs_mask was declared as a single unsigned long on the stack (32 bits on 32-bit architectures). For PSE controllers with more than 32 ports, this causes two problems: - map_event callbacks could wrote bit positions >= 32 via *notifs_mask |= BIT(i), which is undefined behaviour on a 32-bit unsigned long and corrupts adjacent stack memory. - for_each_set_bit(i, ¬ifs_mask, pcdev->nr_lines) treats ¬ifs_mask as a multi-word bitmap and reads beyond the single unsigned long when nr_lines > BITS_PER_LONG. Fix this by moving notifs_mask out of the stack and into struct pse_irq as a dynamically allocated bitmap. It is sized with BITS_TO_LONGS(pcdev->nr_lines) words in devm_pse_irq_helper(), so it is always wide enough regardless of the host word size. [Jakub]: No upstream driver currently supports >=32 ports. Signed-off-by: Kory Maincent Link: https://patch.msgid.link/20260415130300.806152-1-kory.maincent@bootlin.com Signed-off-by: Jakub Kicinski

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
