In the course of fixing up the usages of flexible arrays, Gustavo submitted a patch updating the ehci-fsl driver. However, the patch was wrong because the driver was using the .priv member of the ehci_hcd structure incorrectly. The private data is not supposed to be a wrapper containing the ehci_hcd structure; it is supposed to be a sub-structure stored in the .priv member. Fix the problem by replacing the ehci_fsl structure with ehci_fsl_priv, containing only the private data, along with a suitable conversion macro for accessing it. This removes the problem of having data follow a flexible array member. Reported-by: Gustavo A. R.

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 reStructuredText 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.
