From 85566ca6b6d7e131837cd197a441d98e83146fae Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Mon, 7 Nov 2016 14:52:39 -0700 Subject: [PATCH] ARM: OMAP3: Fix formatting of features printed With the printk cleanups merged into v4.9-rc1, we now get the omap revision printed on multiple lines. Let's fix that and also remove the extra empty space at the end of the features. And let's update things to use scnprintf as suggested by Ivaylo Dimitrov .
