Subject: [PATCH 13/16] wifi: iwlwifi: mvm: change iwl_mvm_flush_sta() API
Date:   Wed, 11 Oct 2023 13:07:28 +0300
Message-Id: <20231011130030.aeb3bf4204cd.I5b0e6d64a67455784bc8fbdaf9ceaf03699d9ce1@changeid>

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

This API is type unsafe and needs an extra parameter to know
what kind of station was passed, so it has two, but really it
only needs two values. Just pass the values instead of doing
this type-unsafe dance, which will also make it better to use
for multi-link.
