[cdi-devel] [PATCH] floppy: Fix step_rate_time for SPECIFY

[Kevin Wolf <kevin@xxxxxxxxxx>]

The code was apparently based on the osdev.org wiki, which confused
seconds and microseconds for step_rate_time, so we're off by a factor of
1000. It's fixed in the wiki for a couple of years now, so it might be
time to fix it in this driver as well.
