[ Upstream commit4ed2f3545c] The error handling code of fsl_ifc_ctrl_probe is problematic. When fsl_ifc_ctrl_init fails or request_irq of fsl_ifc_ctrl_dev->irq fails, it forgets to free the irq and nand_irq. Meanwhile, if request_irq of fsl_ifc_ctrl_dev->nand_irq fails, it will still free nand_irq even if the request_irq is not successful. Fix this by refactoring the error handling code.

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.
