Hi Anusha, Can I ask if this is on anyone's radar as I'm concerned this patch will stall otherwise? I see that the significance of testing with the 4.14 kernel enabled the firmware to be included in the latest Chrome OS kernel ( https://groups.google.com/a/chromium.org/forum/#!topic/chromium-os-reviews/jtpHvZOfZ-Q). It is important to similarly include in the mainline and stable kernels to facilitate various distros that are now raising bug reports (for example: https://bugs.launchpad.net/intel/+bug/1760545).
