From: Chris Wilson Date: Thu, 19 Nov 2020 16:56:12 +0000 (+0000) Subject: drm/i915: Lift i915_request_show() X-Git-Tag: v5.15~1634^2~20^2~153 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1f0e785a9cc09b430d0fbe4e9ac438d43c245815;p=platform%2Fkernel%2Flinux-starfive.git drm/i915: Lift i915_request_show() Extract i915_request_show for reuse in other request chain pretty printers. For a bonus point, quietly change the seqno format from %llx to %lld to match everywhere else.
