[PATCH] arch: c6x: kernel: include "linux/console.h" when 'VT' and 'DUMMY_CONSOLE' enabled.

[Chen Gang]

Need include "linux/console.h" when 'VT' and 'DUMMY_CONSOLE' enabled
(e.g allmodconfig).

The related error:
  arch/c6x/kernel/setup.c: In function ‘setup_arch’:
  arch/c6x/kernel/setup.c:442:2: error: ‘conswitchp’ undeclared (first use in this function)
  arch/c6x/kernel/setup.c:442:2: note: each undeclared identifier is reported only once for each function it appears in
  arch/c6x/kernel/setup.c:442:16: error: ‘dummy_con’ undeclared (first use in this function)

Ah, so you managed to obtain a c6x toolchain. There's none at
https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/ yet :-(

Gr{oetje,eeting}s,

when I'm talking to journalists I just say "programmer" or something like that.

Hmm..., I use:
  [root@dhcp122 linux-next]# rpm -qf /usr/bin/c6x-linux-gnu-gcc
  gcc-c6x-linux-gnu-4.7.1-0.1.20120606.fc17.x86_64

When fix the 3 compiling issues, it almost can pass compiling: during
compiled to fs subsystem, I stopped compilation manually.


Thanks.
