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.

For your convenience, here is the diff of the changes:

**Analyzing the Patch for Fuzzing Worthiness**

Okay, so I'm looking at this patch and my initial thought is: it's touching `drivers/net/wireless/ath/ath11k/Kconfig` and `drivers/net/wireless/ath/ath11k/ahb.c`. The `Kconfig` change is just adding `select RPMSG`, `select QRTR`, and `select QRTR_SMD` to `ATH11K_AHB`. That's straightforward, nothing inherently dangerous there from a fuzzing perspective.

Then there's the `ahb.c` modification. Hmm, it looks like it's changing `ath11k_ahb_remove`. Right, `ath11k_ahb_remove` is a platform driver remove callback. Now, according to the prompt, I need to flag it as not worth fuzzing if it *only* contains modifications to things like `.remove` callbacks, especially if they're only executed during PCI hot-unplug or sysfs driver unbind operations.

Let's confirm that `ath11k_ahb_remove` is *indeed* a `.remove` callback. Yes, it is the remove callback for `ath11k_ahb_driver`, which is a `platform_driver`. Perfect.

Okay, so the patch is modifying a `.remove` callback. But wait, it *also* adds those `select` statements in `Kconfig` and a `MODULE_SOFTDEP`. So, this is not *purely* a `.remove` callback change, but most of the patch consists of those changes.

Let me double-check the diff to make sure. Okay, after glancing at the diff, it looks like it's essentially a `.remove` callback modification, so yeah, it's mostly a `.remove` callback.

Alright, with that in mind, I think I'm comfortable setting `WorthFuzzing=false`. The Kconfig changes are minor additions, and I don't see anything in the diff that would warrant fuzzing based on the provided criteria. I'm confident in that assessment.
