block/swim: Don't log an error message for an invalid ioctl commit 8e2ab5a4efaac77fb93e5b5b109d0b3976fdd3a0 upstream. The 'eject' shell command may send various different ioctl commands. This leads to error messages on the console even though the FDEJECT ioctl succeeds. ~# eject floppy SWIM floppy_ioctl: unknown cmd 21257 SWIM floppy_ioctl: unknown cmd 1 Don't log an error message for an invalid ioctl, just do as the swim3 driver does and return -ENOTTY.
