Instruction: 
You are an expert Linux kernel maintainer.
Your job is to review a provided patch series and determine
if it makes functional changes to the kernel that should be fuzzed.

IMPORTANT: The changes have ALREADY been applied and committed as the HEAD commit in
your workspace. Do NOT rely on your internal knowledge of the kernel. You must actively
use your code access tools to examine the actual source code and confirm any assumptions.

Return WorthFuzzing=false if the patch only contains:
- Modifications to Documentation/, Kconfig files, or code comments.
- Purely decorative changes, such as logging (e.g., pr_err, printk) or tracepoints.
- Changes to numeric constants or macros that do not functionally alter execution flow.
- Code paths that are impossible to reach in virtualized environments like GCE or QEMU,
  even when utilizing software-emulated hardware (e.g., usb gadget, mac80211_hwsim).
- Code in vendor-specific PCIe switch, SmartNIC, or GPU drivers (e.g., mlxsw, pds_core, qed,
  ionic, amdgpu) that require physical PCIe hardware cards not emulated in standard QEMU.
- Driver .remove, .shutdown, or pci_unregister_driver teardown callbacks (e.g., igb_remove)
  that are executed only during PCI hot-unplug or sysfs driver unbind operations.

If it modifies reachable core kernel logic, drivers, or architectures, use your code search
tools to verify the code can be executed, then return WorthFuzzing=true.

When returning WorthFuzzing=true, you MUST ALSO:
1. Extract any specific kernel functions that should be heavily fuzzed into FocusSymbols.
   Avoid listing generic hot-path functions to prevent skewed test distributions.
   Prefer non-static, non-inlined API entrypoint functions over internal static helper functions
   (which are inlined by the compiler and do not have distinct symbol addresses).
2. Identify any specific CONFIG_ options required to properly test this new/modified feature.
   Go and look into the Kconfig files and check for ifdefs around the code, do not make assumptions.
   Also check "depends on" lines in Kconfig to include any non-standard parent subsystem configs
   needed for Kbuild to compile the code statically into vmlinux. List them in the EnableConfigs
   output array, and DO NOT add a 'CONFIG_' prefix (e.g., return "NET_IPV4" instead of "CONFIG_NET_IPV4").
Prefer calling several tools at the same time to save round-trips.


Use set-results tool to provide results of the analysis.
It must be called exactly once before the final reply.
Ignore results of this tool.

**WorthFuzzing Assessment**

Okay, so I've just reviewed this patch and it looks pretty straightforward. It looks like it's just touching a handful of `.yaml` files in the `Documentation/devicetree/bindings/net/` directory. These are, of course, device tree binding documentation files. It's important to remember, binding documentation is very important.

I'm not seeing any actual code changes here, nothing that would impact functionality. Based on my analysis, `WorthFuzzing` should definitely be `false`. Just to be absolutely sure, let's take a quick look at the diff again:

*   `Documentation/devicetree/bindings/net/fsl,gianfar.yaml`: Whitespace fix. Yep.
*   `Documentation/devicetree/bindings/net/microchip,lan966x-switch.yaml`: More whitespace fixes. Got it.
*   `Documentation/devicetree/bindings/net/microchip,sparx5-switch.yaml`: Still just whitespace. Affirmative.
*   `Documentation/devicetree/bindings/net/renesas,rzv2h-gbeth.yaml`: All right, yet more whitespace tweaks.

Alright, that confirms it. All these changes are purely cosmetic and within documentation files. So, with confidence, I'll go ahead and call set-results with `WorthFuzzing=false`.
