power: supply: ab8500: add missing MODULE_DEVICE_TABLE

2021-07-20T14:22:43+00:00

[ Upstream commit dfe52db13ab8d24857a9840ec7ca75eef800c26c ]

This patch adds missing MODULE_DEVICE_TABLE definition which generates
correct modalias for automatic loading of this driver when it is built
as an external module.

power: supply: ab8500: Avoid NULL pointers

2021-07-20T14:22:42+00:00

[ Upstream commit 5bcb5087c9dd3dca1ff0ebd8002c5313c9332b56 ]

Sometimes the code will crash because we haven't enabled
AC or USB charging and thus not created the corresponding
psy device. Fix it by checking that it is there before
notifying.

power: supply: s3c_adc_battery: fix possible use-after-free in s3c_adc_bat_remove()

2021-05-22T08:38:18+00:00

[ Upstream commit 68ae256945d2abe9036a7b68af4cc65aff79d5b7 ]

This driver's remove path calls cancel_delayed_work(). However, that
function does not wait until the work function finishes. This means
that the callback function may still be running after the driver's
remove function has finished, which would result in a use-after-free.

Fix by calling cancel_delayed_work_sync(), which ensures that
the work is properly cancelled, no longer running, and unable
to re-schedule itself.

power: supply: test_power: add missing newlines when printing parameters by sysfs

2020-11-10T09:22:14+00:00

[ Upstream commit c07fa6c1631333f02750cf59f22b615d768b4d8f ]

When I cat some module parameters by sysfs, it displays as follows.
It's better to add a newline for easy reading.

power: supply: check if calc_soc succeeded in pm860x_init_battery

2020-08-21T08:53:02+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: vexpress: add suppress_bind_attrs to true

2020-06-20T08:23:24+00:00

commit 73174acc9c75960af2daa7dcbdb9781fc0d135cb upstream.

Make sure that the POWER_RESET_VEXPRESS driver won't have bind/unbind
attributes available via the sysfs, so lets be explicit here and use
".suppress_bind_attrs = true" to prevent userspace from doing something
silly.
