Dear maintainers,

I get this type of error way too often. What's the most desirable thing
here?

1 - Make it "(5 << 8)" so checkpatch doesn't complain, which will leave
the coding style inconsistent with the surrounding lines.

2 - Drive-by fix all the bits around it so everybody in the same
definition has nice spaces, 2.a: in the same patch, 2.b: in a separate
patch.

3 - Just ignore the checkpatch message, push code as-is.

4 - Blacklist this check from checkpatch.

5 - Submit a separate patch fixing all the spacing errors on i915_reg.h
once and for all. Live happily ever after.

6 - Submit a separate patch converting everything to BIT() on
i915_reg.h.


Thanks,
Paulo
