Subject: migration/vmstate: Remove redundant statement in vmstate_save_state_v()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=600fe89d6e627a18a01f4b7aef15d84efdb81548;p=qemu.git

migration/vmstate: Remove redundant statement in vmstate_save_state_v()

The "ret" has been assigned in all branches. It didn't need to be
 assigned separately.

Clang static code analyzer show warning:
  migration/vmstate.c:365:17: warning: Value stored to 'ret' is never read
                ret = 0;
