Subject: [PATCH v2 0/5] MTK MDP driver cleanups to prep for futher work

It most notably converts an array of MDP components to a list instead,
but also removes some unused fields.

This series of patches does some cleanup in preparation for futher work
so that hardware video decode works on 4.19 and later kernels. We are
planning on adding a dummy driver for the relevant MDP components that
will be bound together using the component framework, which will enable
calls to set up IOMMUs and LARBs, and make calls into pm_runtime.

Changes in v2:
- remove unnecessary error handling labels in favor of err_m2m_register
- rebase onto linux-next/master to pick up

Eizan Miyamoto (5):
  [media] mtk-mdp: remove mtk_mdp_comp.regs from mtk_mdp_comp.h
  [media] mtk-mdp: handle vb2_dma_contig_set_max_seg_size errors during
  [media] mtk-mdp: handle vpu_wdt_reg_handler() errors during probe
  [media] mtk-mdp: convert mtk_mdp_dev.comp array to list
  [media] mtk-mdp: Remove and supporting functionality
