backlight: pm8941: Add NULL check in wled_configure()
[ Upstream commit e12d3e1624a02706cdd3628bbf5668827214fa33 ]
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: f86b77583d88 ("backlight: pm8941: Convert to using %pOFn instead of device_node.name")
