Guo Ren 16b6d9525d riscv: stacktrace: Fixup ftrace_graph_ret_addr retp argument commit `5c3022e4a6` upstream. The 'retp' is a pointer to the return address on the stack, so we must pass the current return address pointer as the 'retp' argument to ftrace_push_return_trace(). Not parent function's return address on the stack.

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.
