The parameter's origin type is long.  On an i386 architecture, it can
easily be larger than 0x80000000, causing this function to convert it to a
sign-extended u64 type.  Change the type to unsigned long so we get the
correct result.

Fix kconfig unmet dependency warning.  BACKLIGHT_CLASS_DEVICE depends on
BACKLIGHT_LCD_SUPPORT, so select the latter along with the former.

When no floppy is found the module code can be released while a timer
function is pending or about to be executed.

CPU0                                  CPU1
      floppy_init()
timer_softirq()
   spin_lock_irq(&base->lock);
   detach_timer();
   spin_unlock_irq(&base->lock);
   -> Interrupt
del_timer();
        return -ENODEV;
                                      module_cleanup();
   <- EOI
   call_timer_fn();
   OOPS

Use del_timer_sync() to prevent this.
