Is somebody interested in fixing these compile errors? As nobody answered to my emails where I proposed this fix more than half year ago and asked for opinion... https://lore.kernel.org/r/20211204022131.bmhla4gkph7s7hy2@pali/ https://lore.kernel.org/r/20211205123209.lyx76daqdwzqwex4@pali/ https://lore.kernel.org/r/20211226215135.blcnafbuwhrq5ram@pali/ https://lore.kernel.org/r/20220113134938.3tx7iiukphvazvsq@pali/ https://lore.kernel.org/r/20220308184851.jmw2xvrapy5wzwof@pali/ If nobody is interested then please STOP sending me these Intel "0-DAY CI Kernel Test Service" emails.
