[PATCH 4.14 115/191] clk: bcm2835: add missing release if devm_clk_hw_register fails

[Greg Kroah-Hartman]

From: Navid Emamdoost <navid.emamdoost@xxxxxxxxx>

[ Upstream commit f6c992ca7dd4f49042eec61f3fb426c94d901675 ]

In the implementation of bcm2835_register_pll(), the allocated pll is
leaked if devm_clk_hw_register() fails to register hw. Release pll if
devm_clk_hw_register() fails.
