>Subject: [PATCH] qlnx: qlnxe: Fix kernel address leakage in qlnx_rdma.c
>
>In function qlnx_rdma_deregister_if,
>the address of object rdma_if will be printed out.
>rdma_if is the address of a global variable qlnxr_drv,
>which is passed from dev/qlnx/qlnxr/qlnxr_os.c
>A kernel address leakage happens.
>Fix this by removing the printf statement.
