Subject: [PATCH] wifi: mac80211: clean up FILS discovery change flags handling
Date: Mon, 29 Jan 2024 19:57:39 +0100
Message-ID: <20240129195739.e340a7d5e7c6.I1dfcca32d43dce903494a2c474844491682671b4@changeid>

From: Johannes Berg <johannes.berg@intel.com>

It doesn't make sense to return BSS change flags in an int, as
they're a bigger type. For this particular function it still
works OK, but clean it up to avoid future errors (or copying
this code in a broken way.)
