Description
In the Linux kernel, the following vulnerability has been resolved:
usb: ulpi: fix double free in ulpi_register_interface() error path
When device_register() fails, ulpi_register() calls put_device() on
ulpi->dev.
The device release callback ulpi_dev_release() drops the OF node
reference and frees ulpi, but the current error path in
ulpi_register_interface() then calls kfree(ulpi) again, causing a
double free.
Let put_device() handle the cleanup through ulpi_dev_release() and
avoid freeing ulpi again in ulpi_register_interface().
