Subject: [PATCH v2 1/2] drm/amdkfd: Move the ignore_crat check before the CRAT table get
Date: Wed, 26 Aug 2020 16:29:15 +0800	[thread overview]
Message-ID: <1598430556-18788-1-git-send-email-guohanjun@huawei.com> (raw)

If the ignore_crat is set to non-zero value, it's no point getting
the CRAT table, so just move the ignore_crat check before we get the
CRAT table.
