The Tegra30 CPUIDLE driver has intention to check whether primary CPU was the last CPU that entered LP2 (CC6) idle-state, but that functionality never got utilized because driver never supported the CC6 state for the case where any secondary CPU is online. The new cpuidle driver will properly support CC6 on Tegra30, including the case where secondary CPUs are online, and that knowledge about what CPUs entered into CC6 won't be needed at all because new driver will use different approach by making use of the coupled idle-state and explicitly parking secondary CPUs before entering into CC6. Thus this patch is just a minor cleanup change.

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.
