This just looks like a bug that S_IFREG was passed in the "mode" argument.

Your change in part 2 doesn't really affect much here.

  debugfs_create_blob()
    debugfs_create_file_unsafe()
      __debugfs_create_file()

which does:

	if (!(mode & S_IFMT))
                	mode |= S_IFREG;
        	BUG_ON(!S_ISREG(mode));

So this is a fine cleanup. But your patch description about ensuring that
the file remains read-only isn't accurate. Your change didn't affect the mode
of this file.
