Description

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

misc: microchip: pci1xxxx: fix double free in the error handling of gp_aux_bus_probe()

When auxiliary_device_add() returns error and then calls
auxiliary_device_uninit(), callback function
gp_auxiliary_device_release() calls ida_free() and
kfree(aux_device_wrapper) to free memory. We should't
call them again in the error handling path.

Fix this by skipping the redundant cleanup functions.
