In hwsim_dump_radio_nl(), when genlmsg_put() on line 3617 fails, hdr is
assigned to NULL. Then hdr is used on lines 3622 and 3623:
genl_dump_check_consistent(cb, hdr);
genlmsg_end(skb, hdr);
Thus, possible null-pointer dereferences may occur.
To fix these bugs, hdr is used here when it is not NULL.
This bug is found by a static analysis tool STCheck written by us.

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.
