[PATCH V2 0/2] Added debugfs node initialization and null pointer detection.

[Yibin Ding <Yibin.Ding@unisoc.com>]

From: Yibin Ding <Yibin.ding@unisoc.com>

The two debugfs nodes (/sys/kernel/debug/interconnect/test_client/dst_node,
src_node) do not initialize the character pointers before creation. For
such uninitialized nodes, direct access will cause a crash due to accessing
a null pointer.
For example, directly execute the following command after booting:
    cat /sys/kernel/debug/interconnect/test_client/dst_node.

Therefore, for the problem nodes, it is necessary to add initialization
operations and null pointer detection when accessing.

  interconnect: Add character pointer initialization
  debugfs: Fix crash problem caused by accessing uninitialized nodes
