SubjectRe: [PATCH v4 0/7] drm/mediatek: fix cursor issue and apply CMDQ in MTK DRM
From
Date
Hi, Bibby:

I've tried to apply this series to 5.5-rc1, but there are many
conflicts. Please resend this series based on 5.5-rc1.

And I've found that if I config CONFIG_MTK_CMDQ=m, the code inside
'#ifdef CONFIG_MTK_CMDQ' would not be built. I think you should change
this to '#if IS_ENABLED(CONFIG_MTK_CMDQ)'.

Regards,
CK
