[Qemu-devel] [PATCH 1/2] milkymist-uart: use qemu_chr_fe_write_all() instead of qemu_chr_fe_write()

[Antony Pavlov <antonynpavlov@gmail.com>]

Here is a quote from the qemu-devel maillist:

<quote author="Peter Crosthwaite"
 url="http://lists.nongnu.org/archive/html/qemu-devel/2013-08/msg04748.html">
  qemu_chr_fe_write() is capable of returning 0
  to indicate EAGAIN (and friends) and you don't
  handle this.
</quote>

Just change it to qemu_chr_fe_write_all() to fix.
