Subject: [PATCH AUTOSEL 5.6 055/606] clk: ti: clkctrl: Fix Bad of_node_put within clkctrl_get_name

From: Tero Kristo <t-kristo@...com>

commit e1f9e0d28ff025564dfdb1001a7839b4af5db2e2 upstream.

clkctrl_get_name incorrectly calls of_node_put when it is not really
doing of_node_get. This causes a boot time warning later on:

[    0.000000] OF: ERROR: Bad of_node_put() on /ocp/interconnect@...00000/segmen
t@...arget-module@...0/cm_core_aon@...pu-cm@.../ipu1-clkctrl@20

Fix by dropping the of_node_put from the function.
