From 574502caed4c11c7bbb6b4532a8bb544f626f2dc Mon Sep 17 00:00:00 2001 From: Bhaktipriya Shridhar Date: Tue, 22 Mar 2016 20:25:55 +0530 Subject: staging: rtl8188eu: os_dep: usb_intf: Clean up tests if NULL returned on failure Some functions like kmalloc/kzalloc return NULL on failure. When NULL represents failure, !x is commonly used.
