floppy: cleanup: do not iterate on current_fdc in do_floppy_init()
There's no need to iterate on current_fdc in do_floppy_init() anymore, in the first case it's only used as an array index to access fdc_state[], so let's get rid of this confusing assignment. The second case is a bit trickier because user_reset_fdc() needs to already know current_fdc when called with drive==-1 due to this call chain: user_reset_fdc() lock_fdc() set_fdc() drive<0 ==> new_fdc = current_fdc Note that current_drive is not used in this code part and may even not match a unit belonging to current_fdc. Instead of passing -1 we can simply pass the first drive of the FDC being initialized, which is even cleaner as it will allow the function chain above to consistently assign both variables.
