[PATCH] branch: remove unused parameter to create_branch()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The name parameter to create_branch() has been unused since commit
55c4a673070f ("Prevent force-updating of the current branch"). Remove
the parameter and adjust the callers accordingly. Also remove the
parameter from the function's documentation comment.
