Subject: [PATCH] clk: renesas: r9a06g032: Repair grave increment error
Git-commit: 02693e11611e082e3c4d8653e8af028e43d31164
Patch-mainline: v6.2-rc1
References: git-fixes

If condition (clkspec.np != pd->dev.of_node) is true, then the driver
ends up in an endless loop, forever, locking up the machine.
