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.
