There's a zero day mistake in the megaraid driver in that the code that obtains the version number does a >> 8 on a char quantity. This >>8 causes a sparse warning because it always produces zero. Al Viro suggested these shifts should be >> 4 thus treating the firmware version as a BCD quantity. However, in the interests of safety we've elected to replace the >> 8 quantities with an explicit zero, thus quieting the sparse warning while preserving the same (albeit incorrect) version number as had previously been seen.
