From 0f646b63a1b2ede7885e45cf6e986128e001f91b Mon Sep 17 00:00:00 2001 From: Paul Cercueil Date: Thu, 28 Dec 2017 14:07:07 +0100 Subject: serial: core: Make uart_parse_options take const char* argument The pointed string is never modified from within uart_parse_options, so it should be marked as const in the function prototype.
