In the probe function, in case of error, resources allocated in 'lp8788_setup_adc_channel()' must be released. This can be achieved easily by using the devm_ variant of 'iio_channel_get()'. This has the extra benefit to simplify the remove function and to axe the 'lp8788_release_adc_channel()' function which is now useless.

Modern device tree bindings are supposed to be created as YAML-files in accordance with dt-schema. This commit replaces SYSCON reboot-mode legacy bare text bindings with YAML file. As before the bindings file states that the corresponding dts node is supposed to be compatible "syscon-reboot-mode" device and necessarily have an offset property to determine which register from the regmap is supposed to keep the mode on reboot.

Add POWER_SUPPLY_TYPE to the uevent env for power supply. Type is a property of all power supplies and there is a sysfs entry for it but it is not included in the properties array of the power supply so explicitly add it to the udev env. Signed-off-by:

Reduce the number of touch points to add a new enum property to the power_supply class by mapping the array of text values to the device attribute descriptor. A new enum property can now added by creating an array with the text values named POWER_SUPPLY_${PROPNAME}_TEXT and adding POWER_SUPPLY_ENUM_ATTR(${PROPNAME}) to the power_supply_attrs array.

Use designated initializers for the sysfs power supply text values. This will help ensure that the text values are kept in sync with the enum values from power_supply.h. Signed-off-by:

Make the device attribute list used to create sysfs attributes more robust by decoupling the list order from order of the enum defined in power_supply.h. This is done by using a designated initializer in the POWER_SUPPLY_ATTR macro. Signed-off-by:

In function power_supply_add_hwmon_sysfs(), psyhw->props is allocated by bitmap_zalloc(). But this pointer is not deallocated when devm_add_action fail, which lead to a memory leak bug. To fix this, we replace devm_add_action with devm_add_action_or_reset. Cc: stable@kernel.org Fixes: e67d4dfc ("power: supply: Add HWMON compatibility layer") Signed-off-by:

The battery full capacity can be affected by the temperature or the servicing time or other factors, so some platforms will track the real battery full capacity in charger manager service.

regmap is a library function that gets selected by drivers that need it. No driver modules should depend on it. Depending on REGMAP_I2C makes this driver only build if another driver already selected REGMAP_I2C, as the symbol can't be selected through the menu kernel configuration.
