From 323e9a18d6e195f44eaaa3d3fe92fce9073fe298 Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Sat, 8 Jul 2023 04:03:55 +0300 Subject: drm/msm/mdp5: use devres-managed allocation for pipe data Use devm_kzalloc to create pipe data structure. This allows us to remove corresponding kfree and drop mdp5_pipe_destroy() function.
