From e44a45ae7b7f7c7a4ebd6aa39b703bf2b97fe848 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Sun, 3 Jun 2007 13:50:40 -0700 Subject: [PATCH] SPI dynamic busid generation bugfix Fix SPI dynamic bus ID assignment to start at 2^15-1 rather than a negative number. Valid bus ids are supposed to be positive, and are (now) stored in an 's16' value.
