From 2e30d14f12421f39329faefd5ae92b02cc9ff255 Mon Sep 17 00:00:00 2001 From: Fengguang Wu Date: Wed, 4 Dec 2013 20:36:31 -0800 Subject: [PATCH] USB: fix coccinelle warnings drivers/usb/host/ehci-mv.c:181:26-27: WARNING comparing pointer to 0, suggest !E /c/kernel-tests/src/cocci/drivers/usb/host/ehci-mv.c:181:26-27: WARNING comparing pointer to 0 Compare pointer-typed values to NULL rather than 0 Semantic patch information: This makes an effort to choose between !x and x == NULL. !x is used if it has previously been used with the function used to initialize x. This relies on type information. More type information can be obtained using the option -all_includes and the option -I to specify an include path.
