[ Upstream commit e3ea1b4847e49234e691c0d66bf030bd65bb7f2b ]
If device_register() returns error in pccardd(), it leads two issues:
1. The socket_released has never been completed, it will block
pcmcia_unregister_socket(), because of waiting for completion
of socket_released.
2. The device name allocated by dev_set_name() is leaked.
Fix this two issues by calling put_device() when device_register() fails.
socket_released can be completed in pcmcia_release_socket(), the name can
be freed in kobject_cleanup().

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.
