Hello,

Thanks for your contribution! I applied it, after adjusting a few
things, see below.

An entry in the DEVELOPERS file was missing.

This is not really useful, as it doesn't prevent a build failure. So
instead, I've added...

This:

+       # We need at least one audio backend
+       select BR2_PACKAGE_ALSA_LIB if \
+              !BR2_PACKAGE_PULSEAUDIO && \
+              !BR2_PACKAGE_GSTREAMER1

This was incorrect: the file is named "LGPL". I only realized this
after pushing, so I fixed up in a follow-up commit.

Thanks!
