unload path but outside lock to avoid the WARN_ON condition of performing
dma_free_attr within the lock. However this caused race condition while
command completion via multiple paths causing system crash. Hence complete the command early in unload path but within the lock to
avoid race condition.

Chenyuan Yang discovered that the USB Gadget subsystem in the Linux kernel did not properly check for the device to be enabled before writing. A local attacker could possibly use this to cause a denial of service. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.
