It is crazy all the things that get compiled in !CONFIG_PRINTK. We
definitely need to fix that after this rework.
As for this warning, anyone have anything against something like:
#ifdef CONFIG_PRINTK
static bool console_emit_next_record(struct console *con, bool *handover, int cookie)
{
... implementation ...
}
#else
static bool console_emit_next_record(struct console *con, bool *handover, int cookie)
{
*handover = false;
return false;
}
#endif
