vedio: backlight: Add NULL check in wled_configure devm_kasprintf() can return a NULL pointer on failure,but this wled->name returned value in wled_configure is not checked. Add NULL check in wled_configure, to handle kernel NULL pointer dereference error. This is similar to the commit 050b23d081da.
