Hi Sam：
sorry，My reply was late.
I commited to the following commit (d6781e490179 - (HEAD -> tmp, tag:
drm-misc-next-2019-08-03) drm/pl111: Drop special pads config check (3
weeks ago) <Linus Walleij>)
I don't know why you executed the error.
- Can you paste your mistakes?
I used the following command to join patch.
0005-v5-2-2-drm-panel-Add-Boe-Himax8279d-MIPI-DSI-LCD-pan.patch did
not change the code.
I just adjusted the form of commit according to your suggestions.
so you can skip this patch.
Thank you for your guidance. If there are any questions. I hope you
can point them out. I will modify it very quickly.
Thanks.
