[PATCH 6.1 16/86] leds: trigger: Remove unused function led_trigger_rename_static()

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Heiner Kallweit <hkallweit1@gmail.com>

[ Upstream commit c82a1662d4548c454de5343b88f69b9fc82266b3 ]

This function was added with a8df7b1ab70b ("leds: add led_trigger_rename
function") 11 yrs ago, but it has no users. So remove it.
