Subject: sparse warning about endianness mismatch on 0xffff assignment

Hi,

The following code causes a sparse warning about " incorrect type in assignment (different base types)"

__le16 var = 0xFFFF;


What would be the best way of fixing this warning?

a) __le16 var = cpu_to_le16(0xFFFF);
b) __le16 var = (__force __le16) 0xFFFF;
c) Ignore the warning and/or fix the sparse tool to not warn about endianness mismatch on an "all 1s" assignment

thanks,
-Sathya
