4.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: Finn Thain <[email protected]> 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.
