[Xen-devel] [PATCH v4 1/5] xen/arm: earlyprintk: move early_flush in early_puts

[Julien Grall <julien.grall@xxxxxxxxxx>]

early_puts function will be exported to be used in the console code. To
avoid loosing characters (see why in commit cafdceb "xen/arm: avoid lost
characters with early_printk), early_flush needs to be called in this
function.
