[PATCH] hweight: typecast return types

Make hweight() macros return unsigned int for 8,16,32 bits,
instead of requiring callers to do that.

drivers/input/joystick/analog.c:414: warning: int format, different type arg (arg 3)
drivers/input/joystick/analog.c:414: warning: int format, different type arg (arg 4)
drivers/input/joystick/analog.c:418: warning: int format, different type arg (arg 4)

Note:  does not address parisc, s390, or sparc64...
waiting for comments.
