From: Tao Jin <tao-j@xxxxxxxxxxx> commit 264fb03497ec1c7841bba872571bcd11beed57a7 upstream. For this specific device on Lenovo Thinkpad X12 tablet, the verbs were dumped by qemu running a guest OS that init this codec properly. After studying the dump, it turns out that the same quirk used by the other Lenovo devices can be reused. The patch was tested working against the mainline kernel.
