From: Suniel Mahesh <sunil.m@xxxxxxxxxxxx>
le16_to_cpu() accepts argument of type __le16 and cpu_to_le16()
returns an argument of type __le16. This patch fixes:
(a) the type of the variable that end's up getting return from
cpu_to_le16().
(b) the member types of struct hfa384x_host_scan_request_data,
struct hfa384x_bytestr32 and struct hfa384x_hscan_result_sub.
The following type mismatch warnings reported by sparse
have been fixed:
warning: incorrect type in assignment (different base types)
warning: cast to restricted __le16
