Bluetooth: btrtl: Fix a error code in rtl_load_config()
We accidentally return success if the kmemdup() fails. It results in a NULL dereference in the caller. Fixes: 1110a2dbe698 ("Bluetooth: btrtl: Add RTL8822BE Bluetooth device") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
