From 266191aa8d14b84958aaeb5e96ee4e97839e3d87 Mon Sep 17 00:00:00 2001 From: Luiz Augusto von Dentz Date: Thu, 16 Sep 2021 13:10:48 -0700 Subject: Bluetooth: Fix passing NULL to PTR_ERR Passing NULL to PTR_ERR will result in 0 (success), also since the likes of bt_skb_sendmsg does never return NULL it is safe to replace the instances of IS_ERR_OR_NULL with IS_ERR when checking its return.
