The upstream code changed the DSD detection recently, so your patch
doesn't apply.  In short, check whether you get fp->dsd_raw set.  If
yes, we can apply the vendor check instead of vendor:device pair
check.

Please resubmit the patch with the correction, and don't forget to add
your sign-off line (see Documentation/process/submitting-patches.rst).
It's a legal requirement for taking the patch to upstream.


thanks,

Takashi
