Subject: [PATCH 0/3] USB Audio gadget endianness fixes

Audio gadget refactoring patches touched few function
files and triggered kbuild test robot verification
who found some endianness issues by sparse tool.

Since most of these issues existed from beginning
in f_uac2 and f_uac1_legacy drivers (and were inherited
be f_uac1), it seems nobody run audio gadgets
on big-endian systems.

I fixed only f_uac1/f_uac2 issues leaving leagacy uac1
driver untouched. USB audio headers also were updated.

I tested patches only on LE system because I have no
big-endian hardware. Also there is no anymore
endianness warnings from sparse during kernel build.

For big endian case tested only build which also
doesn't produce sparse warnings anymore.

Ruslan Bilovol (3):
  include: usb: audio: specify exact endiannes of descriptors
  usb: gadget: f_uac1: endianness fixes.
  usb: gadget: f_uac2: endianness fixes.
