GCC 4.8 is spitting out uninitialized-variable warnings against
"drivers/net/wireless/rtlwifi/rtl8192de/dm.c".  

drivers/net/wireless/rtlwifi/rtl8192de/dm.c:941:31: 
error: 'ofdm_index_old[1]' may be used uninitialized in this
function [-Werror=maybe-uninitialized]
     rtlpriv->dm.ofdm_index[i] = ofdm_index_old[i];

This patch adds initialization to the variable and properly sets its value.

I thought this had already been fixed, but apparently not.

Acked-by: Larry Finger <Larry.Finger@lwfinger.net>

This patch is missing a Signed-off-by line...

That would be perfectly fine.  Or, you can just acknowledge that you
intended for it to be there and I can add it myself.

It's in wireless-next...

commit ec71997eff2231098212a99934c0fb987a9e6b04
Author: Yunlian Jiang <yunlian@google.com>

    rtlwifi: initialize local array and set value.
    
    GCC 4.8 is spitting out uninitialized-variable warnings against
    "drivers/net/wireless/rtlwifi/rtl8192de/dm.c".
    
    drivers/net/wireless/rtlwifi/rtl8192de/dm.c:941:31:
    error: 'ofdm_index_old[1]' may be used uninitialized in this
    function [-Werror=maybe-uninitialized]
         rtlpriv->dm.ofdm_index[i] = ofdm_index_old[i];
    
    This patch adds initialization to the variable and properly sets its value.
