From d59e609d6568ba5ab23c256f412ac5ec360722c1 Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Mon, 1 Nov 2010 15:25:16 -0400 Subject: arch/tile: avoid __must_check warning on one strict_strtol check For the "initfree" boot argument it's not that big a deal, but to avoid warnings in the code, we check for a valid value before allowing the specified argument to override the kernel default.
