Commit41320b18a0("scsi: snic: Fix possible memory leak if device_add() fails") fixed the memory leak caused by dev_set_name() when device_add() failed. However, it did not consider that 'tgt' has already been released when put_device(&tgt->dev) is called. Remove kfree(tgt) in the error path to avoid double free of 'tgt' and move put_device(&tgt->dev) after the removed kfree(tgt) to avoid a use-after-free.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
