This is a snapshot of my -mm patch queue. Uploaded at random hopefully more than once a week.

You will need quilt to apply these patches to the latest Linus release (5.x or 5.x-rcY). The series file is in broken-out.tar.gz and is duplicated in https://ozlabs.org/~akpm/mmotm/series

The file broken-out.tar.gz contains two datestamp files: .DATE and .DATE-yyyy-mm-dd-hh-mm-ss. Both contain the string yyyy-mm-dd-hh-mm-ss, followed by the base kernel version against which this patch series is to be applied.

Thanks for the report.

This is only visible with CONFIG_DRM_I915_WERROR=y which depends on COMPILE_TEST=n. We use the "HDRTEST" and -Werror for development and CI to keep the driver clean, but it's not really intended for general consumption. Usually when something like this even hits the tree it's because of a merge mishap somewhere down the line.
