Subject: [PATCH] clk: qcom: common: fix legacy board-clock registration
Git-commit: 43a51019cc8ff1b1cd2ba72e86563beb40d356fc
Patch-mainline: v4.15-rc1
References: bsc#1051510

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")
