+Subject: wifi: rtlwifi: 8192de: correct checking of IQK reload
+
+From: Ping-Ke Shih <pkshih@realtek.com>
+
+commit 93fbc1ebd978cf408ef5765e9c1630fce9a8621b upstream.
+
+Since IQK could spend time, we make a cache of IQK result matrix that looks
+like iqk_matrix[channel_idx].val[x][y], and we can reload the matrix if we
+have made a cache. To determine a cache is made, we check
+iqk_matrix[channel_idx].val[0][0].
+
+The initial commit 7274a8c22980 ("rtlwifi: rtl8192de: Merge phy routines")
+make a mistake that checks incorrect iqk_matrix[channel_idx].val[0] that
+is always true, and this mistake is found by commit ee3db469dd31
+("wifi: rtlwifi: remove always-true condition pointed out by GCC 12"), so
+I recall the vendor driver to find fix and apply the correctness.
+
+Fixes: 7274a8c22980 ("rtlwifi: rtl8192de: Merge phy routines")
