bq2415x_charger: Fix style issues

Normally I just ask to resubmit the patch with the issues fixed, but N900

/*

  This is platform data for bq2415x chip. It contains default board voltages

  and currents which can be also later configured via sysfs. If value is -1

  then default chip value (specified in datasheet) will be used.



  Value resistor_sense is needed for for configuring charge and termination

  current. It it is less or equal to zero, configuring charge and termination

  current will not be possible.



  Function set_mode_hook is needed for automode (setting correct current limit

  when charger is connected/disconnected or setting boost mode). When is NULL,

  automode function is disabled. When is not NULL, it must have this prototype:



    int (*set_mode_hook)(

      void (*hook)(enum bq2415x_mode mode, void *data),

      void *data)



  hook is hook function (see below) and data is pointer to driver private data



  bq2415x driver will call it as:



    platform_data->set_mode_hook(bq2415x_hook_function, bq2415x_device);



  Board/platform function set_mode_hook return non zero value when hook

  function was successful registered. Platform code should call that hook

  function (which get from pointer, with data) every time when charger was

  connected/disconnected or require to enable boost mode. bq2415x driver then

  will set correct current limit, enable/disable charger or boost mode.



  Hook function has this prototype:



    void hook(enum bq2415x_mode mode, void *data);



  mode is bq2415x mode (charger or boost)

  data is pointer to driver private data (which get from set_charger_type_hook)



  When bq driver is being unloaded, it call function:



    platform_data->set_mode_hook(NULL, NULL);



  (hook function and driver private data are NULL)



  After that board/platform code must not call driver hook function! It is

  possible that pointer to hook function will not be valid and calling will

  cause undefined result.
