Problems with cx18

[Mauro Carvalho Chehab <mchehab@redhat.com>]

Hi Devin/Andy/Jean,

The cx88-alsa and cx18-drivers are broken: the driver depend of request_modules that doesn't exist
when !CONFIG_MODULES, and has some wrong __init annotations.

The sq905c has a warning.

I'm compiling it with:
	make ARCH=i386 allmodconfig drivers/media/|grep -v "^  CC" |grep -v "^  LD"

Those are the errors found:

drivers/media/video/cx18/cx18-driver.c:252: warning: ‘request_modules’ used but never defined

This is often because cx18_alsa_load lacks a __init 
annotation or the annotation of snd_cx18_init is wrong.

Please fix.
