Subject: Re: [PATCH] drm/bridge: it6505: Add caching for EDID

Hi Robert,

Thanks for the review.

I didn't see this patch on drm-misc-next, but my another patch merged
instead: https://cgit.freedesktop.org/drm/drm-misc/commit/?id=5eb9a4314053bda7642643f70f49a2b415920812

Did something go wrong? Or is it me missing something?

Regards,
Pin-yen
