[PATCH 2/4] USB: EHCI: Cleanup and rewrite ehci_vdgb().

From: David Daney
Date: Tue Jan 25 2011 - 12:59:56 EST


The vdbg macro is not used anywhere so it can be removed.

With pre-release GCC-4.6, there are several complaints of variables
that are 'set but not used' caused by the ehci_vdbg() macro expanding
to something that does not contain any of its arguments. We can quiet
this warning by rewriting ehci_vdbg() as a variadic static inline that
does nothing.
