From: Chris Wilson Date: Fri, 27 Sep 2019 21:17:48 +0000 (+0100) Subject: drm/i915/selftests: Distinguish mock device from no wakeref X-Git-Tag: v5.10.7~3692^2~43^2~51 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4e18ca703f2167d8bcb7f736271744131e3c390b;p=platform%2Fkernel%2Flinux-rpi.git drm/i915/selftests: Distinguish mock device from no wakeref On systems that have no runtime-pm, we mark the wakeref as being -1. We therefore cannot use that value for the mock-gt indicator, so opt for -ENODEV instead. The wakeref should never be an error value -- one hopes!
