[Q-e-developers] dv_of_drho optional arguments

[Lorenzo Paulatto]

Hello,
I have noticed that the subroutine dv_of_drho in LR_Modules has an optional 
argument. However, this subroutine does not have an explicit interface (i.e. 
it is not in a module), which can cause problems. It does indeed cause 
problems with xlf.

There are two possible solutions:
1. put the subroutine in a module
2. make the argument non optional

As the subroutine is used in several codes (phonon, tddft) I want to ask your 
opinion before proceeding

cheers
