Subject: [PATCH] of: export of_find_next_cache_node() for modules

The qcom-cpufreq-nvmem module uses of_find_next_cache_node() function,
so export it to be available to the modules.

Fixes: 7683a63c08ff ("cpufreq: qcom-nvmem: create L2 cache device")
Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@...aro.org>
---

This patch fixes the discrepancy caused by the patch for the
qcom-cpufreq-nvmem. I'd like to ask for this patch to be also merged via
the cpufreq tree.
