linux-next: build failure after merge of the tty tree

[Stephen Rothwell]

Hi all,

After merging the tty tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

drivers/tty/serial/fsl_lpuart.c: In function 'lpuart_poll_init':
drivers/tty/serial/fsl_lpuart.c:642:29: error: unused variable 'sport' [-Werror=unused-variable]
  642 |         struct lpuart_port *sport = container_of(port,
      |                             ^~~~~
drivers/tty/serial/fsl_lpuart.c: In function 'lpuart32_poll_init':
drivers/tty/serial/fsl_lpuart.c:696:29: error: unused variable 'sport' [-Werror=unused-variable]
  696 |         struct lpuart_port *sport = container_of(port, struct lpuart_port, port);
      |                             ^~~~~
cc1: all warnings being treated as errors

Caused by commit
