[Qemu-devel] [PATCH] pci: Remove unneeded null pointer check


From: Stefan Weil
Subject: [Qemu-devel] [PATCH] pci: Remove unneeded null pointer check
Date: Sat, 15 Jan 2011 19:01:03 +0100

With bm == NULL, other code in the same function would crash.

This bug was reported by cppcheck:
hw/ide/pci.c:280: error: Possible null pointer dereference: bm
