[PATCH] Simplify yenta code

From: Linas Vepstas
Date: Mon Oct 01 2007 - 14:41:38 EST



Simplify some of the resource detection logic in yenta_socket.
This patch results in the same run-time behaviour as the
current code, but does so with fewer lines of code. This
makes the logical flow of the code a bit easier to understand.
