[Intel-gfx] [PATCH v15 00/16] drm/i915: Implement HDCP2.2

[C, Ramalingam]

Tomas,

Lkp issue is complaining about the header drm/i915_mei_hdcp_interface.h, Which is already merged in drm-tip through below commit. So don’t think this is a genuine issue. May be this build was tried in different tree, where this commit is not added yet?

commit 1626eab70ebc61d015e69a4bc3479d9228539343
Author: Ramalingam C <ramalingam.c at intel.com>

    drm/i915: header for i915 - MEI_HDCP interface

v15 is now part of github.

Best Regards,
Ramalingam C
