This is something coverity spotted: in cadenc_uart_xmit(), the code assumes that qemu_chr_fe_write() always returns the number of bytes written, and subtracts it from the tx_count. However it can also return a negative value indicating an error.
Could one of you fix this please? Skipping the adjustment of tx_count and the memmove() if ret is negative should do I think. thanks -- PMM
