floppy: cleanup: make reset_fdc_info() not rely on current_fdc anymore
Now the fdc is passed in argument so that the function does not use current_fdc anymore. Link: https://lore.kernel.org/r/20200331094054.24441-11-w@1wt.eu Signed-off-by: Willy Tarreau <w@1wt.eu> Signed-off-by: Denis Efremov <efremov@linux.com>
