[ Upstream commit371975b0b0] Changed1dcd67825re-worked the struct fsi_slave initialisation in fsi_slave_init, but introduced a few inconsitencies: the slave->dev is now registered through cdev_device_add, but we may kfree() the device out from underneath the cdev registration. We may also leave an IDA allocated. This change fixes the error paths, so that we kfree() only before the device is registered with the core code. We also move the smode write to before we start creating proper devices, as it's the most likely to fail. We also remove the IDA-allocated minor on error, and properly clean up the of_node.

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.
