From a696d768c1274d667be86abe72869461b9fe0073 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 29 Feb 2016 15:25:49 -0700 Subject: [PATCH] dm: cbfs: Fix handling of invalid type The comment for file_cbfs_type() says that it returns 0 for an invalid type. The code appears to check for -1, except that it uses an unsigned variable to store the type. This results in a warning on 64-bit machines. Adjust it to make the meaning clearer. Continue to handle the -1 case since it may be needed.
