Subject: [PATCH] drm/amd/display: optimize code runtime a bit
Date: Mon, 21 Sep 2020 04:42:42 -0700 [thread overview]
Message-ID: <20200921114244.20506-1-bernard@vivo.com> (raw)
Static function dal_ddc_i2c_payloads_destroy is only called
in dal_ddc_service_query_ddc_data, the parameter is &payloads
, there is no point NULL risk, so no need to check.
This change is to make the code run a bit fast.
