usb: misc: ljca: Fix double free in error handling path

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

usb: misc: ljca: Fix double free in error handling path

When auxiliary_device_add() returns error and then calls

auxiliary_device_uninit(), callback function ljca_auxdev_release

calls kfree(auxdev->dev.platform_data) to free the parameter data

of the function ljca_new_client_device. The callers of

ljca_new_client_device shouldn't call kfree() again

in the error handling path to free the platform data.

Fix this by cleaning up the redundant kfree() in all callers and

adding kfree() the passed in platform_data on errors which happen

before auxiliary_device_init() succeeds .
