Subject: [PATCH 4.17 05/56] ACPICA: Drop leading newlines from error messages

4.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

commit a0d5f3b69af7733f3173a8e19d51f68a08017c76 upstream.

Commit 5088814a6e93 (ACPICA: AML parser: attempt to continue loading
table after error) unintentionally added leading newlines to error
messages emitted by ACPICA which caused unexpected things to be
printed to the kernel log.  Drop these newlines (which effectively
reverts the part of commit 5088814a6e93 adding them).

Fixes: 5088814a6e93 (ACPICA: AML parser: attempt to continue loading table after error)
