Commit 2284eec5053d ("block: introduce blkdev_get_zone_info()")
introduced the report_active field in struct blk_report_zones_args so
that open and closed zones can be reported with the condition
BLK_ZONE_COND_ACTIVE in the case of a cached report zone.
However, the args pointer to a struct blk_report_zones_args that is
passed to disk_report_zones() can be NULL, e.g. in the case of internal
report zones operations for device mapper zoned targets.
Fix disk_report_zones() to make sure to check that the args is not null
before updating a zone condition for cached zone reports.

README
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.
