Axel Haslam 8d6fbe9bf9 greybus: uart: Use a fifo to send data to the modules ... The firmware now buffers data instead of blocking while the transfer is sent, and the write operation cannot sleep. Instead of using gb_transfer_sync (which sleeps) in the write callback, buffer data in a fifo and send it from from a work queue. The write_room callback will will report 1 byte less that what is really available in the fifo, to leave space for extra characters that may be added by the tty layer.
