From 4b9960d052840072b59548b866db5f21d0adcf28 Mon Sep 17 00:00:00 2001 From: Tomas Winkler Date: Fri, 11 Nov 2016 03:00:08 +0200 Subject: [PATCH] mei: constify buffer in the write functions calls The write buffer should not by modified so make it constant. Also hitchhike some style fixes on the way in the interface and rename mei_me_write_message to mei_me_hbuf_write for consistency.
