power: supply: check if calc_soc succeeded in pm860x_init_battery

2020-08-19T06:24:01+00:00

[ Upstream commit ccf193dee1f0fff55b556928591f7818bac1b3b1 ]

clang static analysis flags this error

88pm860x_battery.c:522:19: warning: Assigned value is
  garbage or undefined [core.uninitialized.Assign]
                info->start_soc = soc;
                                ^ ~~~
soc is set by calling calc_soc.
But calc_soc can return without setting soc.

So check the return status and bail similarly to other
checks in pm860x_init_battery and initialize soc to
silence the warning.

power: supply: lp8788: Fix an error handling path in 'lp8788_charger_probe()'

2020-06-24T15:48:42+00:00

[ Upstream commit 934ed3847a4ebc75b655659c4d2349ba4337941c ]

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.

power: supply: bq24257_charger: Replace depends on REGMAP_I2C with select

2020-06-24T15:48:17+00:00

[ Upstream commit 87c3d579c8ed0eaea6b1567d529a8daa85a2bc6c ]

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.

power: supply: core: fix memory leak in HWMON error path

2020-06-22T07:33:03+00:00

commit 1d7a7128a2e9e1f137c99b0a44e94d70a77343e3 upstream.

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.

change email address for Pali Rohár

2020-04-10T22:36:22+00:00

For security reasons I stopped using gmail account and kernel address is
now up-to-date alias to my personal address.

People periodically send me emails to address which they found in source
code of drivers, so this change reflects state where people can contact
me.

2020-04-09T04:25:49+00:00

Pull chrome platform updates from Benson Leung:

  cros-usbpd-notify and cros_ec_typec:
   - Add a new notification driver that handles and dispatches USB PD
     related events to other drivers.
   - Add a Type C connector class driver for cros_ec

  CrOS EC:
   - Introduce a new cros_ec_cmd_xfer_status helper

  Sensors/iio:
   - A series from Gwendal that adds Cros EC sensor hub FIFO support

  Wilco EC:
   - Fix a build warning.
   - Platform data shouldn't include kernel.h

  Misc:
   - i2c api conversion complete, with i2c_new_client_device instead of
     i2c_new_device in chromeos_laptop.
   - Replace zero-length array with flexible-array member in
     cros_ec_chardev and wilco_ec
   - Update new structure for SPI transfer delays in cros_ec_spi

power: twl4030: Use scnprintf() for avoiding potential buffer overflow

2020-03-11T22:20:32+00:00

Since snprintf() returns the would-be-output size instead of the
actual output size, the succeeding calls may go beyond the given
buffer limit.  Fix it by replacing with scnprintf().

power: supply: bq27xxx_battery: Silence deferred-probe error

2020-03-11T22:08:07+00:00

The driver fails to probe with -EPROBE_DEFER if battery's power supply
(charger driver) isn't ready yet and this results in a bit noisy error
message in KMSG during kernel's boot up. Let's silence the harmless
error message.
