Konstantin Komarov 39aef9080f fs/ntfs3: avoid calling run_get_entry() when run == NULL in ntfs_read_run_nb_ra() 
[ Upstream commit c5226b96c0 ]

When ntfs_read_run_nb_ra() is invoked with run == NULL the code later
assumes run is valid and may call run_get_entry(NULL, ...), and also
uses clen/idx without initializing them. Smatch reported uninitialized
variable warnings and this can lead to undefined behaviour. This patch
fixes it.

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 reStructuredText 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.
