    x86: earlyprintk: Fix regression to handle serial,ttySn as 1 arg · ea3acb19
    Jason Wessel authored
    Commit c9530948 ("early_printk: Allow more than one early console")
    introduced a regression in the parsing of the earlyprintk= kernel
    arguments.
    
    If you specify "earlyprintk=serial,ttyS0,115200" as a kernel
    argument, the "serial,ttyS" should be parsed as a single argument
    and not as "serial" and then "ttyS".
    
    Also update the documentation to reflect you can specify the ttyS
    directly without the "serial" argument.
