From 23b89436030e64196a1bc317901d08edd54fb772 Mon Sep 17 00:00:00 2001

Subject: [PATCH] staging: bcm2835-audio: use anonymous union in struct
 vc_audio_msg

commit 9c2eaf7da855d314a369d48b9cbf8ac80717a1d0 upstream.

In this case explicitly naming the union doesn't help overall code
comprehension and clutters it.
