Subject: xilinx_uartlite: Accept input after rx FIFO pop
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=80625b97b52836b944a6438e8e3e9d992e6a00b6;p=qemu.git

xilinx_uartlite: Accept input after rx FIFO pop

The device return false from the can receive function when the FIFO is
full. This mean the device should check for buffered input whenever a byte is
popped from the FIFO.
