Subject: [PATCH 5.6 109/166] leds: core: Fix warning message when init_data

From: Ricardo Ribalda Delgado <ribalda@...nel.org>

[ Upstream commit 64ed6588c2ea618d3f9ca9d8b365ae4c19f76225 ]

The warning message when a led is renamed due to name collition can fail
to show proper original name if init_data is used. Eg:

[    9.073996] leds-gpio a0040000.leds_0: Led (null) renamed to red_led_1 due to name collision

Fixes: bb4e9af0348d ("leds: core: Add support for composing LED class device names")
