Description
In the Linux kernel, the following vulnerability has been resolved:
Input: synaptics-rmi4 - fix GPF in suspend and resume when unbound
Transport drivers (such as rmi_i2c and rmi_spi) invoke
rmi_driver_suspend() and rmi_driver_resume() on their child rmi_dev
device during system power management events. However, transport drivers
are fully registered and operational even if the physical RMI driver
failed to bind or probe the rmi_dev device.
When rmi_driver_suspend() or rmi_driver_resume() is called on an unbound
rmi_dev, dev_get_drvdata() returns NULL. Calling rmi_disable_irq() or
rmi_enable_irq() without driver data attached causes a NULL pointer
dereference and General Protection Fault when attempting to lock
data->enabled_mutex.
Fix this by checking if driver data is attached to rmi_dev in
rmi_driver_suspend() and rmi_driver_resume(), exiting early if
no driver data is present.
