+Subject: tty: serial: fsl_lpuart: Fix unused variable 'sport' build warning
+
+From: Sherry Sun <sherry.sun@nxp.com>
+
+commit 9f8fe348ac9544f6855f82565e754bf085d81f88 upstream.
+
+Remove the unused variable 'sport' to avoid the kernel build warning.
+
+Fixes: 3cc16ae096f1 ("tty: serial: fsl_lpuart: use port struct directly to simply code")
+Reported-by: kernel test robot <lkp@intel.com>
