net: bcmasp: fix double disable of clk

2026-03-21T02:07:28+00:00

Switch to devm_clk_get_optional() so we can manage the clock ourselves. We dynamically control the clocks depending on the state of the interface for power savings. The default state is clock disabled, so unbinding the driver causes a double disable.

net: bcmasp: fix double free of WoL irq

2026-03-21T02:07:28+00:00

We do not need to free wol_irq since it was instantiated with devm_request_irq(). So devres will free for us.

Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00+00:00

This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds

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

net: bcmasp: streamline early exit in probe

2026-01-27T02:58:22+00:00

Streamline the bcmasp_probe early exit. As support for other functionality is added(i.e. ptp), it is easier to keep track of early exit cleanup when it is all in one place.

net: bcmasp: clean up some legacy logic

2026-01-27T02:58:22+00:00

Removed wol_irq check. This was needed for brcm,asp-v2.0, which was removed in previous commits. Removed bcmasp_intf_ops. These function pointers were added to make it easier to implement pseudo channels. These channels were removed in newer versions of the hardware and were never implemented.

net: bcmasp: Add support for PHY-based Wake-on-LAN

2025-10-16T00:45:52+00:00

If available, interrogate the PHY to find out whether we can use it for Wake-on-LAN. This can be a more power efficient way of implementing that feature, especially when the MAC is powered off in low power states.
