David,

The patch below was sent to John Linville yesterday. Obviously, it didn't get included before he
pushed to you. With this patch, all the debugfs names become static, and avoid the namespace clash
with b43. In addition, Michael Buesch has a similar patch pending for b43.

Larry
========================================

There are additional sparse warnings in b43legacy. None of them result
in program errors, but are fixed for completeness.
