Gerrit submit change after abandoning its parent

There is a few options and it depends if you want to include the changes of patchset-1.

• You only want the changes from patchset-2? Checkout master and cherry-pick patchset-2, commit -amend and push again
• You want to include changes from patchset-1 and 2? In this case you may want to combine the two patchsets, easiest is to do a git reset HEAD~2 and commit again, don't forget to copy the Change-ID of your last commit to be able to continue that review

change A被废弃，change B报错

1. 只想要B：

• 切换到其他分支，修改代码，提交到目标分支
• cherry-pick

2. A B都要：

• git reset HEAD^^
• 再次提交，复制最后一次提交的Change-ID以便于可以继续给gerrit 进行代码审查。
