compat_ioctl: Supress "unknown cmd" message on serial /dev/console
After the commit fb07a5f8 ("compat_ioctl: remove all VT ioctl handling"), I got this error message on 64-bit mips kernel with 32-bit busybox userland: ioctl32(init:1): Unknown cmd fd(0) cmd(00005600){t:'V';sz:0} arg(7fd76480) on /dev/console The cmd 5600 is VT_OPENQRY. The busybox's init issues this ioctl to know vt-console or serial-console. If the console was serial console, VT ioctls are not handled by the serial driver. And by quick search, I found some programs using VT_GETMODE to check vt-console is available or not.
