[PATCH 4/4] crypto: caam - fix warning in APPEND_MATH_IMM_u64

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Tudor Ambarus <tudor.ambarus@xxxxxxxxxxxxx>

An implicit truncation is done when using a variable of 64 bits
in MATH command:

warning: large integer implicitly truncated to unsigned type [-Woverflow]

Silence the compiler by feeding it with an explicit truncated value.
