From dfb7ef7d84fa45270b0138dbe6ab4316b03cc724 Mon Sep 17 00:00:00 2001 From: Pavan Savoy Date: Fri, 10 Sep 2010 15:58:55 -0400 Subject: staging: ti-st: fix kim platform device id Platform devices tend to have id as -1 when only 1 device exist and a value >=0 when multiple devices exist, since we plan to store all these platform devices if multiple exist, there was a requirement to have id to be >=0. The patch fixes this problem.
