From: Eric Biggers <ebiggers@xxxxxxxxxx>
sm3_neon_transform() is called via indirect function calls. This
function needs to use SYM_TYPED_FUNC_START instead of SYM_FUNC_START to
cause type hashes 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: c50d32859e70 ("arm64: Add types to indirect called assembly functions")
