On architectures which have symbol prefixes, depmod emits lots of false
warnings like this:
WARNING: $module.ko needs unknown symbol $symbol
This is because depmod isn't being passed the -P <symbol_prefix>
arguments to specify the symbol prefix to ignore. This option is
included since the 3.13 release of module-init-tools.
Update scripts/depmod.sh to take extra arguments which are passed
through directly to depmod, and update the main Makefile to pass
-P $(CONFIG_SYMBOL_PREFIX to scripts/depmod.sh, but only if
CONFIG_SYMBOL_PREFIX is set and non-empty.
scripts/depmod.sh also drops the -P arguments if depmod --version
reports module-init-tools with a version number < 3.13.

OK.

You can replace the test with a simple

Thanks for the suggestion. It would be much cleaner, but unfortunately I
tried this on module-init-tools 3.3-pre2 and module-init-tools 3.9 and
both still return success.

Indeed, depmod had the modutils fallback, so it did not fail on unknown
options immediately. So the version parsing is inevitable. Thanks for
checking.

scripts/Makefile.lib just does:
ifdef CONFIG_SYMBOL_PREFIX
so you should do the same
that said, cmd_depmod is just a shell command. and you're running another
script helper (depmod.sh). how about passing it unconditionally ?
cmd_depmod = ... -P "$(CONFIG_SYMBOL_PREFIX)"
since the default will be "no prefix", using -P "" is the same thing.

Yep, I could do this, but depmod.sh would need modifying to drop it if
the prefix is empty, otherwise you get the following from depmod:
FATAL: -P only takes a single char
I don't mind adding that, but what do you think?
