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
