[ Upstream commitf3c45c045e] While we pass uuid_null intentionally to ffa_partition_probe in ffa_setup_partitions to get the count of the partitions, it must not be uuid_null in ffa_partition_info_get which is used by the ffa_drivers to fetch the specific partition info passing the UUID of the partition. Fix ffa_partition_info_get by passing the received uuid down to ffa_partition_probe so that the correct partition information is fetched.

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.
