Julia,

I would like to gently remind that we should consider applying this patch to v6.8
because it also helps to fix the newly introduced coccicheck warning in v6.8-rc1

> /usr/bin/spatch -D patch --very-quiet --cocci-file scripts/coccinelle/api/device_attr_show.cocci --no-includes --include-headers --patch . --dir arch/x86/events/intel -I ./arch/x86/include -I ./arch/x86/include/generated -I ./inclu
de -I ./arch/x86/include/uapi -I ./arch/x86/include/generated/uapi -I ./include/uapi -I ./include/generated/uapi --include ./include/linux/compiler-version.h --include ./include/linux/kconfig.h --jobs 4 --chunksize 1
warning: rp: metavariable STR not used in the - or context code <<< new warning
6 files match

Thanks
Zhijian
