How to combine two same blocks into a single one?

How can I use a single block in this:

devise_parameter_sanitizer.for(:sign_up) do |u|
  u.permit(:full_name, :email, :password, :password_confirmation)
end
devise_parameter_sanitizer.for(:account_update) do |u|
  u.permit(:full_name, :email, :password, :password_confirmation)
end
