From: Arnd Bergmann <arnd@xxxxxxxx>
This function is now called from a cpufreq driver, but that breaks the
build when the caller is in a loadable module, because of a missing
export:
ERROR: modpost: "of_find_next_cache_node" [drivers/cpufreq/qcom-cpufreq-nvmem.ko] undefined!
Export this as a GPL-only symbol, like the other related functions in
this file.
Fixes: 7683a63c08ff5 ("cpufreq: qcom-nvmem: create L2 cache device")
Fixes: a3e31b4588443 ("of: Move definition of of_find_next_cache_node into common code.")
