[PATCH] ASoC: SOF: mediatek: initialize panic_info to zero

[YC Hung]

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.

      commit: 7bd220f2ba9014b78f0304178103393554b8c4fe

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
