[resend] [patch] ide-floppy - software eject not working with LS-120 drive

This is a resend because I didn't get any reply before.

The problem (eject not working on ATAPI LS-120 drive) is caused by 
idefloppy_ioctl() function which *first* tries generic_ide_ioctl() and 
*only* if it fails with -EINVAL, proceeds with the specific ioctls. The 
generic eject command fails with something other than -EINVAL and the 
specific one is never executed.
This patch fixes it by first going through the internal ioctls and only
trying generic_ide_ioctl() if none of them matches.
