From 96a1616c85ae62fc13aff85a34effb4b2477b7ce Mon Sep 17 00:00:00 2001 From: Eric Blake Date: Tue, 23 Feb 2016 14:14:33 -0700 Subject: qapi-dealloc: Reduce use outside of generated code No need to roll our own use of the dealloc visitors when we can just directly use the qapi_free_FOO() functions that do what we want in one line. In net.c, inline net_visit() into its remaining lone caller. After this patch, test-visitor-serialization.c is the only non-generated file that needs to use a dealloc visitor, because it is testing low level aspects of the visitor interface.

For better legibility in that patch, and less need for line wrapping, it's better to use a temporary variable to reduce the effect of a layout change to just the variable initializations, rather than every reference within an InputEvent. There was one instance in hid.c:hid_pointer_event() where the code was referring to evt->u.rel inside the case label where evt->u.abs is the correct name; thankfully, both members of the union have the same type, so it happened to work, but it is now cleaner.
