From 6de6e5c4becb5494d09d44ce4db1c54dc43afbae Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Fri, 18 Jun 2021 08:14:23 +0200 Subject: [PATCH] mxser: remove else from LSR bits checks UART_LSR_SPECIAL is composed of UART_LSR_BI, UART_LSR_PE, UART_LSR_FE, UART_LSR_OE. So status cannot be anything else. Remove the unused else branch.
