Description

In the Linux kernel, the following vulnerability has been resolved: power: supply: wm97xx: Fix NULL pointer dereference in power_supply_changed() In probe(), request_irq() is called before allocating/registering a power_supply handle. If an interrupt is fired between the call to request_irq() and power_supply_register(), the power_supply handle will be used uninitialized in power_supply_changed() in wm97xx_bat_update() (triggered from the interrupt handler). This will lead to a NULL pointer dereference since Fix this racy NULL pointer dereference by making sure the IRQ is requested after the registration of the power_supply handle. Since the IRQ is the last thing requests in the probe() now, remove the error path for freeing it. Instead add one for unregistering the power_supply handle when IRQ request fails.
