Subject: [PATCH] wifi: iwlfifi: fix -Wunused-const-variable gcc warning
Date:   Mon, 19 Jun 2023 13:00:25 +0300
Message-ID: <20230619100030.284920-1-dmantipov@yandex.ru>

Fix the following gcc 13.1 warning observed with W=1:

drivers/net/wireless/intel/iwlwifi/dvm/rs.c:207:39: warning:
‘iwl_rate_mcs’ defined but not used [-Wunused-const-variable=]

This table is actually used in 'rs_sta_dbgfs_scale_table_read()'
only if CONFIG_MAC80211_DEBUGFS is enabled.
