Oh right, I wasn't sure what the pattern was.  It does warn about int_t 
types in _some_function declarations, but on closer inspection, it only 
seems to do so when there is a line break before the parameter 
declaration.  For example:

CHECK: Prefer kernel type 'u16' over 'uint16_t'
#519: FILE: drivers/staging/comedi/drivers/s626.c:519:
+			uint16_t chan, int16_t dacdata)
