From d8510553e26bc872b94f6bdc02523bfd7a7c5298 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Mon, 15 Feb 2016 20:12:03 +0100 Subject: arm64/efi: Make strnlen() available to the EFI namespace Changes introduced in the upstream version of libfdt pulled in by commit 91feabc2e224 ("scripts/dtc: Update to upstream commit b06e55c88b9b") use the strnlen() function, which isn't currently available to the EFI name- space. Add it to the EFI namespace to avoid a linker error.
