The diff does not show any pointer dereference so it is hard to understand what you are trying to do with this patch. > Signed-off-by: Shreeya Patel <shreeya.patel23...@gmail.com> > --- > drivers/staging/rtlwifi/base.c | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > diff --git a/drivers/staging/rtlwifi/base.c b/drivers/staging/rtlwifi/base.c > index b88b0e8..5bb8f98 100644 > --- a/drivers/staging/rtlwifi/base.c > +++ b/drivers/staging/rtlwifi/base.c > @@ -781,7 +781,7 @@ static void _rtl_txrate_selectmode(struct ieee80211_hw > *hw, > > struct rtl_priv *rtlpriv = rtl_priv(hw); > struct rtl_mac *mac = rtl_mac(rtl_priv(hw)); > - struct rtl_sta_info *sta_entry = NULL; > + struct rtl_sta_info *sta_entry; Now the pointer just has garbage in it instead of the testable value of NULL. If you are concerned with the dereference perhaps you could add a NULL check, again it's hard to say without seeing the code. It is hard to see how this patch is correct though. Hope this helps, Tobin.
