Subject: [PATCH v2 0/2] staging: rtl8192e: Removing unused arrays
 ..RadioC_A.. and ..ERadioD_A..

The array Rtl8192PciERadioC_Array and ..RadioD.. is only used in function
rtl92e_config_rf_path which is only called in function rtl92e_config_rf.
In function rtl92e_config_rf a termination condition for the loop is set
to priv->num_total_rf_path = RTL819X_TOTAL_RF_PATH = 2. The loop is only
executed with numbers 0 and 1 for eRFPath. So the function 
rtl92e_config_rf_path is only called with eRFPath for 0 and 1 and never
with 2 or 3 that would make the "case RF90_PATH_C:" and 
"case RF90_PATH_D:" be called. Remove resulting dead code.
