Re: [PATCH] floppy: remove redundant assignment to variable st

[Denis Efremov]

Jens, could you please take this one? I thought to send it to you with other
cleanup patches in a merge request, but you already applied rest of the
patches. If you prefer to take it as merge request, it's ok I'll send it
based on your branch for-5.13/drivers.
