[v2,1/2] staging: rtl8192e: Remove unused Array Rtl8192PciERadioC_Array
Commit Message
The array Rtl8192PciERadioC_Array 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 that would make the "case RF90_PATH_C:" be called. Remove
resulting dead code.

Thanks. This explanation is very good. I was expecting that the issue
was in a completely different place so this explanation really helps a
lot.
