Re: [Intel-gfx] [PATCH] drm/i915/ehl: Remove require_force_probe protection

["Pandey, Hariom" <hariom.pandey@intel.com>]

Hi Srinivas,

Take Sunil's help who has recently validated RC6 on EHL DRM tip and found to be passing. If the WA were sporadically failing and if you confirm that RC6 is passing, this patch can be proceeded with. 

Thanks
Hariom Pandey

I told based on what I was seeing on https://intel-gfx-ci.01.org/tree/drm-tip/drmtip-alt.html?
focusing on the issues that are exclusively for ehl and not happening on other platforms.

It looks like workarounds are fine there now. so I'm not sure if it was sporadic thing that day.

for the rc6 there are a few testcases failing around it:
