From b27f07c50a73e34eefb6b1030b235192b7ded850 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 24 Feb 2023 13:36:57 +0100 Subject: [PATCH] wifi: nl80211: fix puncturing bitmap policy This was meant to be a u32, and while applying the patch I tried to use policy validation for it. However, not only did I copy/paste it to u8 instead of u32, but also used the policy range erroneously. Fix both of these issues.
