This define is only used in s5pcsis_irq_handler():

The problem is that "status" is a 32 bit and (0xff<<  28) is larger than
32 bits and that sets off a static checker warning.  I consulted with
Sylwester Nawrocki and the define should actually be (0xf<<  28).

Thanks for the fix, patch added to my tree for v3.14.
