This causes an warning from sparse due to __le16 to u16 conversion. Fix this by using cpu_to_le16() on the two fields in the packet. net/bluetooth/hci_core.c:845:27: warning: incorrect type in assignment (different base types) net/bluetooth/hci_core.c:845:27: expected restricted __le16 [usertype] tx_len net/bluetooth/hci_core.c:845:27: got unsigned short [usertype] le_max_tx_len net/bluetooth/hci_core.c:846:28: warning: incorrect type in assignment (different base types) net/bluetooth/hci_core.c:846:28: expected restricted __le16 [usertype] tx_time net/bluetooth/hci_core.c:846:28: got unsigned short [usertype] le_max_tx_time Signed-off-by: Ben Dooks Signed-off-by: Marcel Holtmann --- diff --git a/net/bluetooth/hci_core.c b/net/bluetooth/hci_core.c index 04bc79359a17..b2559d4bed81 100644 --- a/net/bluetooth/hci_core.c +++ b/net/bluetooth/hci_core.c @@ -842,8 +842,8 @@ static int hci_init4_req(struct hci_request *req, unsigned long opt) if (hdev->le_features[0] & HCI_LE_DATA_LEN_EXT) { struct hci_cp_le_write_def_data_len cp; - cp.tx_len = hdev->le_max_tx_len; - cp.tx_time = hdev->le_max_tx_time; + cp.tx_len = cpu_to_le16(hdev->le_max_tx_len); + cp.tx_time = cpu_to_le16(hdev->le_max_tx_time); hci_req_add(req, HCI_OP_LE_WRITE_DEF_DATA_LEN, sizeof(cp), &cp); }
