From 8132b8d182e3e3c20bb1ba99be0434c43c462286 Mon Sep 17 00:00:00 2001 From: Lucas De Marchi Date: Fri, 7 Jun 2019 02:12:29 -0700 Subject: [PATCH] drm/i915/dmc: remove redundant return in parse_csr_fw() parse_csr_fw() is responsible to set up several fields in struct intel_csr, including the payload. We don't need to assign it again.
