Not really, how about this:

void __init brcmstb_biuctrl_init(void)
{
        int ret;

        setup_hifcpubiuctrl_regs();

        ret = mcp_write_pairing_set();
        if (ret) {
                pr_err("MCP: Unable to disable write pairing!\n");
                return;
        }

#ifdef CONFIG_PM_SLEEP
        register_syscore_ops(&brcmstb_cpu_credit_syscore_ops);
#endif
}

and updating the function prototype accordingly in the header file?
