It seems more complex to have #ifdef guarded logic around a function call to pass or not pass an argument when we that same argument is already defaulted in that function. If the difference between the two paths is primarily the argument, then we can always pass it, making sure that in the case that defaulting would have been used that we pass the same default value. This is now done with assertions. Change-Id: I333eb3f42cb51dfab8584ae8c5aa52ee45c5a9a1 Signed-off-by: Ashod Nakashian <ashod.nakashian@collabora.co.uk>
