The error path has several mistakes
- cdev_del should not be called if cdev_device_add fails
- We must call put_device on all the goto exit paths as that is what frees
the uapi, SRCU and the struct itself.
While we are here consolidate all the uvdev_dev init that cannot fail at
the top.
Fixes: c5c4d92e70f3 ("RDMA/uverbs: Use cdev_device_add() instead of cdev_add()")

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
