    regulator: Rename files for Maxim PMIC drivers · 86cf635a
    Javier Martinez Canillas authored
    Most Maxim PMIC regulator drivers are for sub-devices of Multi-Function
    Devices with drivers under drivers/mfd. But for many of these, the same
    object file name was used for both the MFD and the regulator drivers.
    
    Having 2 different drivers with the same name causes a lot of confusion
    to Kbuild, specially if these are built as module since only one module
    will be installed and also exported symbols will be undefined due being
    overwritten by the other module during modpost.
    
    For example, it fixes the following issue when both drivers are module:
    
    $ make M=drivers/regulator/
      ...
      CC [M]  drivers/regulator//max14577.o
      Building modules, stage 2.
      MODPOST 1 modules
    WARNING: "maxim_charger_calc_reg_current" [drivers/regulator//max14577.ko] undefined!
    WARNING: "maxim_charger_currents" [drivers/regulator//max14577.ko] undefined!
