drivers/tty/hvc/hvc_tile.c: properly return -EAGAIN We were returning zero if no bytes could be written to the Tilera hypervisor console device, but this causes the output to be truncated. By returning -EAGAIN the tty hvc driver will come back and try again, which gives the semantics we want, and avoids dropping console output.
