When using the hierarchical topology and PSCI OSI-mode we may end up overriding the deepest idle-state's ->enter|enter_s2idle() callbacks, but there is no point to also re-assign the CPUIDLE_FLAG_RCU_IDLE for the idle-state in question, as that has already been set when parsing the states from DT. See init_state_node().

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.
