Re: [PATCH v3] scsi: sg: Avoid sg device teardown race

sg_remove_sfp_usercontext() must not use sg_device_destroy() after calling scsi_device_put().

sg_device_destroy() is accessing the parent scsi device request_queue. Which will already be set to NULL when the preceding call to scsi_device_put() removed the last reference to the parent scsi device.

The resulting NULL pointer exception will then crash the kernel.
