Date: Thu, 5 Nov 2020 00:51:34 +0100 From: Rikard Falkeborn <rikard.falkeborn@...il.com> To: Greg Kroah-Hartman <gregkh@...uxfoundation.org> Cc: Jiri Slaby <jirislaby@...nel.org>, Andy Gross <agross@...nel.org>, Bjorn Andersson <bjorn.andersson@...aro.org>, linux-arm-msm@...r.kernel.org, linux-serial@...r.kernel.org, linux-kernel@...r.kernel.org, Rikard Falkeborn <rikard.falkeborn@...il.com> 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.
