From 9c3bd6833a4df1abd9ecd3b51492b8949bf9cd11 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Tue, 15 Aug 2006 00:05:38 -0700 Subject: [IRDA]: Replace hard-coded dev_self[] array sizes with ARRAY_SIZE() Several IR drivers used "for (i = 0; i < 4; i++)" to walk their dev_self[] table. Better to use ARRAY_SIZE(). And fix ali-ircc so it won't run off the end if we find too many adapters. Signed-off-by: Bjorn Helgaas Signed-off-by: Andrew Morton Signed-off-by: David S.
