Subject: RE: [PATCH]"drm: change DRM_MIPI_DSI module type from "bool" to
 "tristate".

Dear Maintainers,

It's needed that DRM Driver module could be removed and reloaded after kernel booting on the projects that I have been working on, and I hope such module type change could be accepted. Looks like Iwai has similar change request as well. Would you please review it and let us know if any concerns?

Regards,
Sun, Jing

Unfortunately, nothing seems to have happened since my last patch due to little interest.  I'd be glad if the patch is revived.

(BTW, I'm traveling in these two weeks, so the further reply will be
 delayed.)


thanks,

Takashi
