Subject: dts_header: initialize SUBSTREAM_LBR size to 0
X-Git-Tag: archive/raspbian/3.0.21-7+rpi1^2~97

dts_header: initialize SUBSTREAM_LBR size to 0

It's a substream and can't work alone, so a size of 0 is legitimate.

Fixes #28773 (Use of uninitialised value)

(cherry picked from commit b23f09b258dc63c2221af502ec856630f68817e5)
