I had not checked, but I see that it does have the same bug.

I only sent this one because the build bot (incorrectly)
blamed one of my recent patches for a regression here.
Which reminds me that I was missing:

Reported-by: kernel test robot <lkp@...el.com>
Link: https://lore.kernel.org/oe-kbuild-all/202305160749.ay1HAoyP-lkp@intel.com/

Should I resend this as a combined patch for both drivers?
