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).

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.
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.
   Do not list too generic configs (we already have them enabled). Only list those that
   specifically cover the modified code. 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.

**Analysis of a Minor Code Modification**

Okay, let's take a look at this patch modifying `drivers/net/wireless/ath/ath12k/wifi7/hw.c`. Right away, I see that it's just adding braces around an `if-else` block and reformatting some comments. My initial impression is that this is purely a stylistic change, but it's always wise to be thorough.

The diff itself is straightforward: the brace insertion is evident, and the comment wrapping is slightly altered. Looking specifically, the condition `tmp_dp->hw_params->iova_mask` remains unchanged, and the assignments to `msdu_copied` using `skb_copy` and `skb_clone` are identical to the original code. The only difference is the added braces and the re-wrapped comment.

Given that this is solely a formatting change, it's safe to conclude there's no functional alteration. Therefore, in the context of fuzzing, this patch isn't going to uncover new behavior or vulnerabilities.

My assessment is that `WorthFuzzing` should definitely be `false` in this case. I'm satisfied that this isn't a code change of any significance and will proceed with that conclusion.
