[PATCH 3/3] qom: Simplify and merge pointer property getters/setters |
|
Date: |
Fri, 9 Oct 2020 15:15:20 -0400 |
Both the property getter and setter for pointer properties can
simply call the visitor functions directly, instead of making
extra copies and requiring additional logic.
Remove the extra copying logic, and merge the getter and setter
functions in object_visit_uint*_ptr() accessors.
