Commit f79f11852831ba8837e82b73364e6f1cd0145499

Authored by Arnd Bergmann
Committed by Linus Torvalds

Exists in master and in 4 other branches v3.2_AM335xPSP_04.06.00.11, v3.2_NEWT335xPSP_04.06.00.11, v3.2_SBC_SMARTMEN, v3.2_SMARCT335xPSP_04.06.00.11

compat_ioctl: ignore RAID_VERSION ioctl 

md ioctls are now handled by the md driver itself, but mdadm
may call RAID_VERSION on other devices as well. Mark the command
as IGNORE_IOCTL so this fails silently rather than printing
an annoying message.
