From 69147121abf569bf3655a2000c6511f1f016d9f8 Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Thu, 21 Mar 2013 12:19:31 +0200 Subject: usb: gadget: net2272: fix sparse warnings Fix the following sparse warnings: drivers/usb/gadget/net2272.c:916:13: warning: Using plain integer as NULL pointer drivers/usb/gadget/net2272.c:1624:9: warning: Using plain integer as NULL pointer drivers/usb/gadget/net2272.c:1552:30: warning: right shift by bigger than source value Note that the last warning is an actual bug, since ep->dma is a one bit value which is shifted by one bit in code.
