genl_family_rcv_msg_attrs_parse() and genl_family_rcv_msg_attrs_free() take a boolean parameter to determine whether allocate/free the family attrs. This is unnecessary as we can just check family->parallel_ops. More importantly, callers would not need to worry about pairing these parameters correctly after this patch. And this fixes a memory leak, as after commitc36f055591("genetlink: fix memory leaks in genl_family_rcv_msg_dumpit()") we call genl_family_rcv_msg_attrs_parse() for both parallel and non-parallel cases.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
