Sorry, we don't do stuff like this.

The driver shall keep the reference to it's old vendor name, and
this is how we've handled similar situations in the past.

And do you know the worst part about this?  You DID in fact
functionally change this driver:

> -#define FW_FILENAME	"idtcm.bin"
> +#define FW_FILENAME	"cm_tcs.bin"

Now everyone would have missing firmware.

So not only is this unacceptable on precedence grounds, and how we
always handle situations like this, it's functionally wrong and would
break things for users.

Please remove this patch and resubmit #1 and #3 as a series for
re-review.

Thank you.
