Subject: [PATCH] drm/mediatek: Find the cursor plane instead of hard coding it

The cursor and primary planes were hard coded.
Now search for them for passing to drm_crtc_init_with_planes

Subject: Re: [PATCH] drm/mediatek: Find the cursor plane instead of hard coding it

Apologies for the confusing thread. Please apply the above patch:
'drm/mediatek: Find the cursor plane instead of hard coding it'
before Sean Paul's original patch:
'drm/mediatek: Ensure the cursor plane is on top of other overlays'

This way authorship is correctly preserved, but we do not introduce the bug.

Thanks

Hi CK,
Thanks for picking this up. Before you send the pull, could you please
reverse the order of these 2 patches? Evan's should come before mine
to prevent a regression.
