[ Upstream commit a4c5a457c6107dfe9dc65a104af1634811396bac ]
for_each_sibling_event() checks leader's ctx but it doesn't have the ctx
yet if it's the leader. Like in perf_event_validate_size(), we should
skip checking siblings in that case.

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.
