cf08d4bc70
This patch does a small cleanup of level zero plugin. Mainly I changed names of variables to use `CamelCase` whenever they relate to our internal structures - not objects coming directly from level zero API etc., so I left some variables and arguments like `zeDevice`, but only if they are directly related to level zero APIs or structures. Added a few `auto *` declarations, but again - only when they refer to our internal objects and not to structures from level zero which might be pointers underneath, but we use them as transparent objects. Also did small cleanup of unused headers, making sure that we include directly what we need rather than use transitive dependencies. @adurang Please let me know if this patch is okay with you, if you think this will cause more harm then it's worth I'll close it. --------- Co-authored-by: Łukasz Plewa <lukasz.plewa@intel.com>
