Subject[PATCH] printk: Modify operators of printed_len
Date
In 8b1742c9c207, we remove printk-recursion detection code in
vprintk_emit(), where it is the first place that printed_len calculated.
After removing above detection, it seems we can directly assign the
result of log_output to printed_len.
