Fix NULL-deference bug, kerneldoc errors, minor coding style error.
Also add a wrapper to avoid having to cast a const pointer to non-const.

Richard Fitzgerald (5):
  debugfs: Prevent NULL dereference reading from string property
  debugfs: Remove kerneldoc that says debugfs_create_str() returns a
    value
  debugfs: Update debugfs_create_str() kerneldoc to warn about pointer
    race
  debugfs: Move debugfs_create_str() export to correct location
  debugfs: Add debugfs_create_const_str()
