sel_make_avc_files() might fail and return a negative errno value on
memory allocation failures. Re-add the check of the return value,
dropped in 66f8e2f03c02 ("selinux: sidtab reverse lookup hash table").
Reported by clang-analyzer:
security/selinux/selinuxfs.c:2129:2: warning: Value stored to
'ret' is never read [deadcode.DeadStores]
ret = sel_make_avc_files(dentry);

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.
