From: chenglang <[e-mail]>

The driver passes structure resp's member a to ib core.
Then, ib core uses container_of() to init resp's all
members. At last, the driver uses resp's member b. The
static check tool CppCheck considers this is an uninitStructMember
bug. Here initialize resp in the driver to avoid this dependence.
