Re: [PATCH 00/27] drm/rockchip: MIPI fixes & improvements

[John Keeping <john@metanate.com>]

D'oh, I got send-email horribly wrong here.  Please ignore the n/27
patches following this message - the n/26 versions are correct.

I won't spam the list with a cleaned-up v2 immediately, but I'll make
extra sure to clean out my working directory when I do send the re-roll!
