[patch] video: cinergyT2 build fix

From: Ingo Molnar
Date: Sun May 04 2008 - 16:34:20 EST



x86.git testing found the following build bug in v2.6.26-rc1:

drivers/built-in.o: In function `cinergyt2_probe':
cinergyT2.c:(.text+0xb6117): undefined reference to `input_allocate_device'
cinergyT2.c:(.text+0xb6230): undefined reference to `input_register_device'
cinergyT2.c:(.text+0xb623d): undefined reference to `input_free_device'

with the following config:

http://redhat.com/~mingo/misc/config-Sun_May__4_22_06_54_CEST_2008.bad

The reason for the bug is that the cinergyT2 driver depends on
CONFIG_INPUT functionality, but if INPUT is modular it's still possible
to build CONFIG_DVB_CINERGYT2=y - which leads to missing symbols.

The solution is to make DVB_CINERGYT2 dependent on INPUT.

[ This solves the build problem - i have not tested the driver on this card. ]
