From 0d66442dfdbd45019c60bb6aeaf2d5eb45534606 Mon Sep 17 00:00:00 2001 From: Rikard Falkeborn Date: Thu, 5 Nov 2020 00:51:34 +0100 Subject: [PATCH] tty: serial: msm_serial: Constify msm_uart_pops The only usage of msm_uart_pops is to assign its address to the ops field in the uart_port struct, which is a pointer to const. Make it const to allow the compiler to put it in read-only memory.
