Description

In the Linux kernel, the following vulnerability has been resolved:

Input: synaptics-rmi4 - fix use after free in rmi_unregister_function()

The put_device() calls rmi_release_function() which frees "fn" so the
dereference on the next line "fn->num_of_irqs" is a use after free.
Move the put_device() to the end to fix this.
