power_supply: ipaq_micro_battery: Check return values in probe

2015-05-06T20:03:45+00:00

commit a2c1d531854c4319610f1d83351213b47a633969 upstream.

The return values of create_singlethread_workqueue() and
power_supply_register() calls were not checked and even on error probe()
function returned 0.

1. If allocation of workqueue failed (returning NULL) then further
   accesses could lead to NULL pointer dereference. The
   queue_delayed_work() expects workqueue to be non-NULL.

2. If registration of power supply failed then during unbind the driver
   tried to unregister power supply which was not actually registered.
   This could lead to memory corruption because
   power_supply_unregister() unconditionally cleans up given power
   supply.

power_supply: ipaq_micro_battery: Fix leaking workqueue

2015-05-06T20:03:45+00:00

commit f852ec461e24504690445e7d281cbe806df5ccef upstream.

during removal.

power_supply: lp8788-charger: Fix leaked power supply on probe fail

2015-05-06T20:03:45+00:00

commit a7117f81e8391e035c49b3440792f7e6cea28173 upstream.

Driver forgot to unregister charger power supply if registering of
battery supply failed in probe(). In such case the memory associated
with power supply leaked.

power_supply: twl4030_madc: Check return value of power_supply_register

2015-05-06T20:03:44+00:00

commit 68c3ed6fa7e0d69529ced772d650ab128916a81d upstream.

The return value of power_supply_register() call was not checked and
even on error probe() function returned 0. If registering failed then
during unbind the driver tried to unregister power supply which was not
actually registered.

This could lead to memory corruption because power_supply_unregister()
unconditionally cleans up given power supply.

power/reset: restart-poweroff: Remove arm dependencies

2015-01-25T21:13:18+00:00

This driver is now arm specific anymore, so there is no need to include
an arm specific include file. Also drop unnecessary depencency on ARM
from Kconfig.

power/reset: st-poweroff: Fix misleading Kconfig description

2015-01-25T21:13:17+00:00

The st-poweroff driver does not really power off the system
but resets it, so Kconfig should not claim that the driver
would handle power-off.

power/reset: st-poweroff: Register with kernel restart handler

2015-01-25T21:13:16+00:00

Register with kernel restart handler instead of setting arm_pm_restart
directly. Select high priority since the restart handler is instantiated
through devicetree, indicating that it should be used if configured.

power/reset: Remove sun6i reboot driver

2015-01-25T21:13:07+00:00

sun6i restart is now handled by its watchdog driver directly,
so this driver is no longer needed.

power/reset: at91: Register with kernel restart handler

2015-01-25T21:12:45+00:00

Register with kernel restart handler instead of setting arm_pm_restart
directly. Register with high priority since the driver unconditionally
overwrites other restart handlers if instantiated.
