Re: arch/parisc/math-emu/driver.c:88:17: sparse: sparse: Using plain integer as NULL pointer

[Chris Down]

The real issue is this:

    ../arch/parisc/math-emu/decode_exc.c: In function 'decode_fpu':
    ../arch/parisc/math-emu/decode_exc.c:49:25: error: expected identifier before numeric constant
       49 | #define fmt             11      /* bits 19 & 20 */
          |                         ^~
    ../include/linux/printk.h:391:34: note: in expansion of macro 'fmt'
      391 |                                 .fmt = __builtin_constant_p(_fmt) ? (_fmt) : NULL, \

And that's why you don't define such shortly named, ambiguous macros. The 
simplest fix is probably just to have this file and others like it use _printk.

I'll send a patch and cc linux-parisc.
