The version of depmod in busybox does not work if two versions of the same kernel version are available, as search paths are not honoured correctly. However, we don't need to actually call depmod as it's done during image building anyway. Change-Id: Idd3cd5854e7c86e7ca1f2b0e50758d7db79ab6e7 Co-Author: matthew.gilliard@hp.com Closes-bug: #1302856
