[PATCH V4 0/3] tty: serial: fsl_lpuart: cleanup lpuart driver

[Sherry Sun]

Do some cleanup for lpuart driver, no functionality change.

Changes in V4:
1. Fix unused variable 'sport' warning in patch#2 reported by kernel test robot.

Changes in V3:
1. Add the change to covert unsigned char to u8 in the first patch as Jiri suggested.

Changes in V2:
1. Add the third patch to rename the register variables as Jiri suggested.

Sherry Sun (3):
  tty: serial: fsl_lpuart: Use u32 and u8 for register variables
  tty: serial: fsl_lpuart: use port struct directly to simply code
  tty: serial: fsl_lpuart: rename register variables more specifically
