[ Upstream commit 727ea61a5028f8ac96f75ab34cb1b56e63fd9227 ]
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.
