In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Free transport channel on IDR failure
If transport channel setup succeeds but the following IDR insertion fails,
the error path destroys the transport device and frees the channel info
without invoking the transport cleanup callback.
Call chan_free() before destroying the device so transport specific
resources such as IRQs, mailbox channels and mapped shared memory are
released consistently with the normal teardown path.
