Merge tag 'modules-for-v5.4-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux
Pull modules fixes from Jessica Yu:
- Revert __ksymtab_$namespace.$symbol naming scheme back to
__ksymtab_$symbol, as it was causing issues with depmod.
Instead, have modpost extract a symbol's namespace from __kstrtabns
and __ksymtab_strings.
- Fix `make nsdeps` for out of tree kernel builds (make O=...) caused
by unescaped '/'.
Use a different sed delimiter to avoid this problem.
* tag 'modules-for-v5.4-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux:
scripts/nsdeps: use alternative sed delimiter
symbol namespaces: revert to previous __ksymtab name scheme
modpost: make updating the symbol namespace explicit
modpost: delegate updating namespaces to separate function
