This is a set of simple cleanups for various drivers. All should be
straightforward.

The last two patches enable compilation on 0-day bot also for three more
drivers. So we should have a better coverage. Actually the last but one
is the result of the last one -- 0-day bot already complained to me.

Jiri Slaby (7):
  serial: sunplus-uart: mark sunplus_console_ports[] static
  serial: xilinx_uartps: return early in cdns_uart_handle_tx()
  serial: xilinx_uartps: cache xmit in cdns_uart_handle_tx()
  serial: zs: use NULL as a pointer, not 0
  serial: qcom: use check for empty instead of pending
  serial: pic32: make SERIAL_PIC32_CONSOLE depend on SERIAL_PIC32=y
  serial: allow COMPILE_TEST for some drivers
