Andy:
Here's what I just got from checkpatch:
ERROR: space prohibited after that '-' (ctx:BxW)
#22: FILE: drivers/usb/host/ehci-sched.c:1419:
+ start += (next - start + period - 1) & (- period);
^
This seems unlikely to be a real style violation. Or if it is, maybe
it shouldn't be. After all, "(0 - period)" would be okay.

2c: I think the recommendation is proper and correct.

I just looked in CodingStyle, and sure enough, there it is in section
3.1. The complaint is hereby withdrawn.
