Subject: Re: [PATCH v3] staging: ks7010: Add null pointer check for skb

Btw, if you have the cross function DB built then Smatch says that the

$ smdb hostif_data_request
[ snip ]
drivers/staging/ks7010/ks_wlan_net.c |   ks_wlan_start_xmit |  hostif_data_request |  PARAM_VALUE |  1 | skb | s64min-(-1),1-s64max
