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. Cc: Matti Vaittinen <mazziesaccount@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> --- ChangeLog v2->v3: - Keep power_supply_put_battery_info() in the bd99954 charger driver: the init data can indeed be dropped after initialization. ChangeLog v1->v2: - Fix two bugs causing compile errors - was hard to get compiler coverage but the build servers stepped in and corrected me. --- drivers/power/supply/ab8500-bm.h | 2 +- drivers/power/supply/ab8500_bmdata.c | 7 +++-- drivers/power/supply/ab8500_btemp.c | 10 +++++-- drivers/power/supply/ab8500_chargalg.c | 16 +++++----- drivers/power/supply/ab8500_fg.c | 18 ++++++----- drivers/power/supply/axp20x_battery.c | 6 ++-- drivers/power/supply/bd99954-charger.c | 24 ++++++++------- drivers/power/supply/bq24190_charger.c | 6 ++-- drivers/power/supply/bq2515x_charger.c | 8 ++--- drivers/power/supply/bq256xx_charger.c | 24 +++++++-------- drivers/power/supply/bq25980_charger.c | 6 ++-- drivers/power/supply/bq27xxx_battery.c | 38 ++++++++++++------------ drivers/power/supply/cw2015_battery.c | 20 ++++++++----- drivers/power/supply/ingenic-battery.c | 14 ++++----- drivers/power/supply/power_supply_core.c | 15 ++++++++-- drivers/power/supply/sc2731_charger.c | 8 ++--- drivers/power/supply/sc27xx_fuel_gauge.c | 22 +++++++------- drivers/power/supply/smb347-charger.c | 34 ++++++++++----------- include/linux/power_supply.h | 2 +- 19 files changed, 153 insertions(+), 127 deletions(-)
