From 52e742f2bee4134f26098d75b796b0408eeee327 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 17 Feb 2020 09:58:35 +0000 Subject: [PATCH] drm/i915/gt: Rearrange code to silence compiler Without selftests enabled, I915_SELFTEST_ONLY becomes a dummy, generating a bare '0'. This causes the compiler to complain about a useless line, and while we could use I915_SELFTEST_DECLARE instead, it is a bit messier. Move the selftest-only code to a helper and make that conditional on having selftests enabled.
