Subject: [PATCH] rtlwifi: rtl892cu: Set limit for pwdb_all
Date: Wed, 2 Apr 2025 15:10:40 +0800 [thread overview]
Message-ID: <20250402071040.3155-1-vulab@iscas.ac.cn> (raw)
In _rtl92c_query_rxphystatus(), the return rtl_query_rxpwrpercentage()
need to be checked. A proper implementation can be found in
_rtl8723be_query_rxphystatus(). Add a value check and set the limit of
pwdb_add as 100.
Fixes: 666e8457fae4 ("rtlwifi: rtl8192cu: Add routine mac")
Cc: stable@vger.kernel.org # v2.6+
