[PATCH 0/1] MR8816: winebus: SDL backend FF effect angle requires 32 bits.

[Rémi Bernon (＠rbernon)]

The max value of a INT16 is 32768, which is less than the 36000
required for a full rotation angle. Change type to INT32 as that
is what the underlying SDL paramerter is.

Rotate by +270 instead of -90 to eliminate negative value fixup too.
