sm3_neon_transform() is called via indirect function calls. Therefore
it needs to use SYM_TYPED_FUNC_START instead of SYM_FUNC_START to cause
its type hash to be emitted when the kernel is built with
CONFIG_CFI_CLANG=y. Otherwise, the code crashes with a CFI failure (if
the compiler didn't happen to optimize out the indirect call).
Fixes: c50d32859e ("arm64: Add types to indirect called assembly functions")

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.
