Subject: [PATCH] ASoC: SOF: mediatek: initialize panic_info to zero
Date: Tue, 13 Dec 2022 19:56:17 +0800	[thread overview]
Message-ID: <20221213115617.25086-1-yc.hung@mediatek.com> (raw)

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.
