Hmm, I am doing something wrong?

   git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git linux-5.13.y
   cd linux-5.13.y/
   git tag|grep v5.13
   v5.13
   v5.13-rc1
   v5.13-rc2
   v5.13-rc3
   v5.13-rc4
   v5.13-rc5
   v5.13-rc6
   v5.13-rc7
   v5.13.1

There is no v5.13.2-rc1. It is my first time with 'git bisect'. Must be
doing something wrong. How can I get the correct git kernel rc version?
