Peter Senna Tschudin 7cd80fc138 tools: usb: ffs-test: Fix build on big endian systems
[ Upstream commit a2b22dddc7 ]

The tools/usb/ffs-test.c file defines cpu_to_le16/32 by using the C
library htole16/32 function calls. However, cpu_to_le16/32 are used when
initializing structures, i.e in a context where a function call is not
allowed.

It works fine on little endian systems because htole16/32 are defined by
the C library as no-ops. But on big-endian systems, they are actually
doing something, which might involve calling a function, causing build
failures, such as:

   ffs-test.c:48:25: error: initializer element is not constant
    #define cpu_to_le32(x)  htole32(x)
                            ^~~~~~~
   ffs-test.c:128:12: note: in expansion of macro ‘cpu_to_le32’
      .magic = cpu_to_le32(FUNCTIONFS_DESCRIPTORS_MAGIC_V2),
               ^~~~~~~~~~~

To solve this, we code cpu_to_le16/32 in a way that allows them to be
used when initializing structures. This fix was imported from
meta-openembedded/android-tools/fix-big-endian-build.patch written by
Thomas Petazzoni <thomas.petazzoni@free-electrons.com>.

README

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.
