Hmmm. The symbol resolution for loading ivtv and cx18 complains about
symbols that all seem to be defined in videodev.ko:
$ cd /lib/modules
$ find . -name "videodev.ko" -exec nm -g --defined-only {} \; -print
The gripe message comes from linux/kernel/module.c when checking symbol
versions. The functions to resolve symbols and check versions want the
CRC values that are stored in here:
$ cd /lib/modules
$ find . \( -name ivtv.ko -o -name cx18.ko \) \
-exec objdump -s -j __versions {} \; -print
to match the ones stored in here:
$ find . -name videodev.ko -exec objdump -s \
-j __kcrctab \
-j __kcrctab_gpl \
-j __kcrctab_gpl_future \
-j __kcrctab_unused \
-j __kcrctab_unused_gpl \
{} \; -print
I apparently don't have CONFIG_MODVERSIONS set, so I can't point you to
exactly where the matching CRC values should be.
The symbol resolution and version checking code in module.c appears to
look for any symbols compiled into the kernel first, and then for
symbols in modules though. So it would be helpful to know if the
symbols in question are compiled into the kernel or not.
On my system:
$ grep video_unregister_device /proc/kallsyms
ffffffff881f8585 u video_unregister_device [ivtv]
ffffffff881f8585 u video_unregister_device [cx18]
ffffffff881fd920 r __ksymtab_video_unregister_device [videodev]
ffffffff881fda00 r __kstrtab_video_unregister_device [videodev]
ffffffff881f8585 T video_unregister_device [videodev]
Shows that the symbol "video_unregister_device" is defined as
text/executable ("T") and provided by the module [videodev] and that the
modules [ivtv] and [cx18] have references to the symbol but don't define
it ("u").
If "video_unregister_device" is built into the kernel you won't see the
[videodev] module name by it.
