Bluetooth: missed cpu_to_le16 conversion in hci_init4_req
It looks like in hci_init4_req() the request is being initialised from cpu-endian data but the packet is specified to be little-endian. 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 <ben.dooks@codethink.co.uk> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
