Henry Martin e12d3e1624 backlight: pm8941: Add NULL check in wled_configure() ...

devm_kasprintf() returns NULL when memory allocation fails. Currently,
wled_configure() does not check for this case, which results in a NULL
pointer dereference.

Add NULL check after devm_kasprintf() to prevent this issue.

Fixes: f86b77583d ("backlight: pm8941: Convert to using %pOFn instead of device_node.name")
