commit c435f0a9
category: bugfix
bugzilla: 107448
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c435f0a9ecb7435e70f447b7231ca52de589b252

-----------------------------------------------

We allocate the iSCSI host workq in iscsi_host_alloc() so iscsi_host_free()
should do the destruction. Drivers can then do their error/goto handling
and call iscsi_host_free() to clean up what has been allocated in
iscsi_host_alloc().
