CVE-2026-93136

bus: mhi: ep: Fix device refcount leak in the error path of MHI device creation

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

bus: mhi: ep: Fix device refcount leak in the error path of MHI device creation

mhi_ep_create_device() takes one device reference for the UL channel and
another for the DL channel after allocating the transfer device. These
references are normally released by mhi_ep_destroy_device() before the
device itself is removed.

If dev_set_name() or device_add() fails, the error path currently drops
only one reference. The remaining channel references keep the device
from being released and leave the channels associated with a device that
was never registered.

Route both failures through a common unwind path that drops the DL
channel reference, the UL channel reference, and the initial reference
from device_initialize().
