commit dfb5394f804ed4fcea1fc925be275a38d66712ab upstream. When kobject_init_and_add() returns an error in the function hfi1_create_port_files(), the function kobject_put() is not called for the corresponding kobject, which potentially leads to memory leak. This patch fixes the issue by calling kobject_put() even if kobject_init_and_add() fails.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
