BTW, you can simply typedef __be16 ubi16_t; etc. and define conversion
functions as cpu_to_ubi16(x) being (__force ubi16_t)cpu_to_be16(x), etc.

sparse will do all checks just fine, you still have bitwise operations
(might or might be not relevant in your case) and for gcc it simply
becomes __be16, etc - i.e. an integer type.
