From 459e794b9b1e0c6be93745344c40364296e7aacd Mon Sep 17 00:00:00 2001 From: Christophe Ricard Date: Sat, 13 Sep 2014 10:28:52 +0200 Subject: [PATCH] NFC: st21nfca: ERR_PTR vs NULL fix "skb" can be NULL here but it can't be an ERR_PTR: - IS_ERR(NULL) return false and skb migth be NULL. - skb cannot be a ERR_PTR as nfc_hci_send_cmd_async it never using such cast. !skb is more appropriate at those places.
