csky: Fixup init_fpu compile warning with __init (12879bda) · Commits · 戴 / test

WARNING: vmlinux.o(.text+0x2366): Section mismatch in reference from the function csky_start_secondary() to the function .init.text:init_fpu() The function csky_start_secondary() references the function __init init_fpu(). This is often because csky_start_secondary lacks a __init annotation or the annotation of init_fpu is wrong. Reported-by:
