It seems they've just cleaned up the documentation, specifically the `@s1g_cap` entry within the `ieee80211_sta_s1g_cap` structure. I remember that file quite well, so I'm double-checking the diff to make sure there's nothing else sneaky in there. Yes, that's it - a simple removal of a duplicated comment. It's just clarifying that `@s1g_cap` is, well, S1G capabilities, and only applies to S1G bands – which, implicitly, is obvious. It's good to keep the documentation tidy, but ultimately, this is a purely cosmetic change. No code is modified, just comments. Therefore, after this very quick review, I'm confident that this change doesn't introduce any risk and I'm marking it as `WorthFuzzing=false`.

**My Assessment of the Patch**

Okay, so I'm looking at this patch for `cfg80211.h`. It seems they've just cleaned up the documentation, specifically the `@s1g_cap` entry within the `ieee80211_sta_s1g_cap` structure.  I remember that file quite well, so I'm double-checking the diff to make sure there's nothing else sneaky in there. *Yes, that's it - a simple removal of a duplicated comment.*  It's just clarifying that `@s1g_cap` is, well, S1G capabilities, and only applies to S1G bands – which, implicitly, is obvious. It's good to keep the documentation tidy, but ultimately, this is a purely cosmetic change. No code is modified, just comments.  Therefore, after this very quick review, I'm confident that this change doesn't introduce any risk and I'm marking it as `WorthFuzzing=false`.
