From 973780011106c534d69c4d25fe0749bd3a5f0b53 Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Sun, 9 Feb 2020 22:05:13 +0900 Subject: [PATCH] tools/bootconfig: Suppress non-error messages Suppress non-error messages when applying new bootconfig to initrd image. To enable it, replace printf for error message with pr_err() macro. This also adds a testcase for this fix.
