From 883c2cfc8bcc0fd00c5d9f596fb8870f481b5bda Mon Sep 17 00:00:00 2001 From: Stuart Yoder Date: Fri, 23 Jul 2010 13:42:44 -0500 Subject: [PATCH] of/flattree: fix of_flat_dt_is_compatible() to match the full compatible string With the current string comparison, a device tree compatible of "foo-bar" would match as compatible with a driver looking for "foo". This patch fixes the function to use the of_compat_cmp() macro so that it does the right thing on all platforms (If sparc ever uses this code, it will still want the strncasecmp() behaviour).
