Subject: [PATCH] drm/i915/gt: return NULL rather than a plain 0 integer
Date:   Sat, 25 Sep 2021 23:12:21 +0100

From: Colin Ian King <colin.king@canonical.com>

Function gen7_ctx_vma returns a pointer to struct i915_vma, so
returning a plain 0 integer isn't good practice. Fix this by
returning a NULL instead.
