Sivan Zohar-Kotzer 8374ac7d69 powercap: dtpm_cpu: Fix NULL pointer dereference in get_pd_power_uw() 
[ Upstream commit 46dc574068 ]

The get_pd_power_uw() function can crash with a NULL pointer dereference
when em_cpu_get() returns NULL. This occurs when a CPU becomes impossible
during runtime, causing get_cpu_device() to return NULL, which propagates
through em_cpu_get() and leads to a crash when em_span_cpus() dereferences
the NULL pointer.

Add a NULL check after em_cpu_get() and return 0 if unavailable,
matching the existing fallback behavior in __dtpm_cpu_setup().

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.
