Subject: [PATCH 4.9 13/47] drm/amdgpu/si: fix ASIC tests

From: Jean Delvare <jdelvare@...e.de>

[ Upstream commit 77efe48a729588527afb4d5811b9e0acb29f5e51 ]

Comparing adev->family with CHIP constants is not correct.
adev->family can only be compared with AMDGPU_FAMILY constants and
adev->asic_type is the struct member to compare with CHIP constants.
They are separate identification spaces.
