From b147de25537652f8dabf40d5165350dad083a28a Mon Sep 17 00:00:00 2001 From: Naushir Patuck Date: Thu, 18 Feb 2021 12:48:24 +0000 Subject: pipeline: raspberrypi: Update the lens shading control in-place Only update the lens shading control if it is present in the ControlList. Add the dmabuf file descriptor to the lens shading control in-place rather than taking a copy.
