Subject: [PATCH 4.14 144/284] tty: hvc: fix return value of __setup handler
From: Randy Dunlap <rdunlap@...radead.org>
[ Upstream commit 53819a0d97aace1425bb042829e3446952a9e8a9 ]
__setup() handlers should return 1 to indicate that the boot option
has been handled or 0 to indicate that it was not handled.
Add a pr_warn() message if the option value is invalid and then
always return 1.
