[Qemu-devel] [PULL v2 03/11] milkymist-uart: use qemu_chr_fe_write_all() instead of qemu_chr_fe_write()

[Michael Walle]

From: Antony Pavlov <antonynpav...@gmail.com>

qemu_chr_fe_write() is capable of returning 0
to indicate EAGAIN (and friends) and we don't
handle this.

Just change it to qemu_chr_fe_write_all() to fix.
