This will be used for communication between the i915 driver and the mei one. Defining it in a stand-alone patch to avoid circualr dependedencies between the patches modifying the 2 drivers. Split out from an original patch from Huang, Sean Z v2: rename the component struct (Rodrigo) Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210924191452.1539378-2-alan.previn.teres.alexis@intel.com
