Hi Jorge,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on sound/for-next]
[also build test WARNING on v4.18-rc5 next-20180719]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

url:    https://github.com/0day-ci/linux/commits/Jorge-Sanjuan/usb-audio-Add-UAC3-Power-Domains/20180719-212009
base:   https://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git for-next
reproduce:
        # apt-get install sparse
        make ARCH=x86_64 allmodconfig
        make C=1 CF=-D__CHECK_ENDIAN__


sparse warnings: (new ones prefixed by >>)

>> sound/usb/stream.c:562:5: sparse: symbol 'snd_usb_add_audio_stream_v3' was not declared. Should it be static?

Please review and possibly fold the followup patch.
