From ba7ffcd4c4da374b0f64666354eeeda7d3827131 Mon Sep 17 00:00:00 2001 From: Randy Dunlap Date: Mon, 28 Feb 2022 14:05:32 -0800 Subject: PM: hibernate: fix __setup handler error handling If an invalid value is used in "resumedelay=", it is silently ignored. Add a warning message and then let the __setup handler return 1 to indicate that the kernel command line option has been handled.
