Branch line commit

I created a branch and did some changes which i need to rollout. but when i want to check in my branch line it wants to update my branch line before i commit. I don't want to have my branch line to contain the changes from mainline. Does anyone know how i can commit my branch line changes only to the branch line.

The update will be from the branch line and not from the mainline. Getting changes from the mainline will require a merge action.
