csky_pmu_event_init is called several times during the perf record
initialzation. After configure the event counter in either kernel
space or user space, csky_pmu_event_init is called twice with no
attr specified. Configuration will be overwritten with sampling in
both kernel space and user space. --all-kernel/--all-user is
useless without this patch applied.

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.
