Subject: [PATCH v6 drm-dp 4/5] drm/hisilicon/hibmc: separate struct of vdac
From: baihan li <libaihan@...wei.com>
Refactored struct hibmc_drm_private to separate VGA module from
generic struct.

ChangeLog:
v3 -> v4:
- separating hibmc_vdac and hibmc_dp changes into separate patche, suggested by Dmitry Baryshkov.
v2 -> v3:
- fix build errors reported by kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202410251136.1m7BlR68-lkp@intel.com/
v1 -> v2:
- deleting struct dp_mode and dp_mode_cfg function, suggested by Dmitry Baryshkov.
- modifying drm_simple_encoder_init function, suggested by Dmitry Baryshkov.
- refactoring struct hibmc_connector, suggested by Dmitry Baryshkov.
- withdrawing the modification in hibmc_kms_init, suggested by Dmitry Baryshkov.
v1:https://lore.kernel.org/all/20240930100610.782363-1-shiyongbang@huawei.com/
