Subject[PATCH 4.14 138/164] clk: qcom: common: fix legacy board-clock registration
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Johan Hovold <johan@kernel.org>


[ Upstream commit 43a51019cc8ff1b1cd2ba72e86563beb40d356fc ]

Make sure to search only the child nodes of "/clocks", rather than the
whole device-tree depth-first starting at "/clocks" when determining
whether to register a fixed clock in the legacy board-clock registration
helper.

Fixes: ee15faffef11 ("clk: qcom: common: Add API to register board clocks backwards compatibly")
