Subject: [PATCH AUTOSEL 6.0 4/7] ASoC: SOF: mediatek: initialize panic_info to zero

From: YC Hung <yc.hung@...iatek.com>

[ Upstream commit 7bd220f2ba9014b78f0304178103393554b8c4fe ]

Coverity spotted that panic_info is not initialized to zero in
mtk_adsp_dump. Using uninitialized value panic_info.linenum when
calling snd_sof_get_status. Fix this coverity by initializing
panic_info struct as zero.
