The structure returned from r600_audio_status() is only partially initialized, and older gcc versions (4.3 and 4.4) warn about this:
drivers/gpu/drm/radeon/r600_hdmi.c: In function 'r600_audio_status': drivers/gpu/drm/radeon/r600_hdmi.c:108: error: 'status.id' is used uninitialized in this function drivers/gpu/drm/radeon/r600_hdmi.c:108: error: 'status.connected' is used uninitialized in this function drivers/gpu/drm/radeon/r600_hdmi.c:108: error: 'status.offset' is used uninitialized in this function This is harmless and surprisingly correct in C99, as the caller only accesses the fields that got initialized, so newer compilers don't warn about it, but initializing the entire structure feels like the right thing to do here and avoids the warning.
