[PATCH 1/2] serial: xilinx_uartps: Fix warnings in the driver

From: Michal Simek
Date: Mon Jun 10 2019 - 04:49:27 EST


From: Nava kishore Manne <nava.manne@xxxxxxxxxx>

This patch fixes the below warning

-->Symbolic permissions 'S_IRUGO' are not preferred.
Consider using octal permissions '0444'.
-->macros should not use a trailing semicolon.
-->line over 80 characters.
-->void function return statements are not generally useful.
-->Prefer 'unsigned int' to bare use of 'unsigned'.

Happy to split it if needed.
