6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Srinivas Pandruvada <srinivas.pandruvada@xxxxxxxxxxxxxxx> [ Upstream commit 8874e414fe78718d0f2861fe511cecbd1cd73f4d ] Add defines to get major and minor version from a TPMI version field value. This will avoid code duplication to convert in every feature driver. Also add define for invalid version field.
