Subject: [PATCH] clk: bcm2835: add missing release if devm_clk_hw_register fails
Git-commit: f6c992ca7dd4f49042eec61f3fb426c94d901675
Patch-mainline: v5.10-rc1
References: git-fixes

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.
