What it is

In the Linux kernel, the following vulnerability has been resolved:

ASoC: rt711-sdca: fix kernel NULL pointer dereference when IO error

The initial settings will be written before the codec probe function.

But, the rt711->component doesn't be assigned yet.

If IO error happened during initial settings operations, it will cause the kernel panic.

This patch changed component->dev to slave->dev to fix this issue.
