Refactor code to use cdev_device_add() and do other minor refactors while modifying these functions as below. 1. Instead of returning generic -1, return an actual error for ib_umad_init_port(). 2. Introduce and use ib_umad_init_port_dev() for sm and umad char devices. 3. Instead of kobj, use more light weight kref to refcount ib_umad_device. 4. Use modern cdev_device_add() single code cut down three steps of cdev_add(), device_create(). This further helps to move device sysfs files to class attributes in subsequent patch. 5. Remove few empty lines while refactoring these functions. 6. Use sizeof() instead of sizeof to avoid checkpatch warning. 7. Use struct_size() for calculation of ib_umad_port.

README
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.
