Linus Walleij f444578d72 power: supply: bq256xx: Handle OOM correctly
Since we now return a pointer to an allocated object we need
to account for memory allocation failure in a separate
error path.

Linus Walleij 25fd330370 power: supply_core: Pass pointer to battery info
The function to retrieve battery info (from the device tree) assumes
we have a static info struct that gets populated by calling into
power_supply_get_battery_info().

This is awkward since I want to support tables of static battery
info by just assigning a pointer to all info based on e.g. a
compatible value in the device tree.

We also have a mixture of static and dynamically allocated
variables here.

Bite the bullet and let power_supply_get_battery_info() allocate
also the memory used for the very top level
struct power_supply_battery_info container. Pass pointers
around and lifecycle this with the psy device just like the
stuff we allocate inside it.

Change all current users over.

As part of the change, initializers need to be added to some
previously uninitialized fields in struct
power_supply_battery_info.

Ricardo Rivera-Matos c3f1813516 power: supply: bq256xx: Fix BQ256XX_NUM_WD_VAL and bq256xx_watchdog_time[] overrun
Corrects BQ256XX_NUM_WD_VAL from value of "8" to "4" and fixes the issue when 'i'
is equal to array size then array index over runs the array
