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

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

From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit b07b6b27a50e3a740c9aa6260ee4bb3ab29515ab ]

The commit in Fixes updated the error handling path of
thunderstrike_create() and the remove function but not the error handling
path of shield_probe(), should an error occur after a successful
thunderstrike_create() call.

Add the missing call. Make sure it is safe to call in the probe error
handling path by preventing the led_classdev from attempting to set the LED
brightness to the off state on unregister.
