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

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

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

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