From 2679534b03a5e1c89652f470906e428b8c971afc Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Fri, 30 Sep 2016 15:57:14 +0200 Subject: libfdt: Add new errors for the overlay code Add a few new error codes to report the failure conditions we might encounter in the overlay application code: - FDT_ERR_BADOVERLAY, when an overlay cannot be parsed, even though its structure is correct - FDT_ERR_NOPHANDLES, when we ran out of available phandles and we cannot use a new phandle without either using an invalid one (-1 or 0), or one already used.
