From 8a17af80e0732cb6ce5e7348dcb2d56a7b870e1d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 22 Oct 2015 18:44:56 +0300 Subject: [PATCH] lib: Skip suspend/hibernate tests if the system doesn't support them MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Do a dry run with rtcwake first to determine if the system even supports the intended suspend state. If not, skip the test. Fixes a bunch of stuff on my BYT FFRD8 that doesn't support S3.
