From 772034b63e9c0caf6c92e31413f2d8df2ee69c88 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Tue, 12 Jul 2016 13:02:17 +0100 Subject: [PATCH] linux-user: Check dump_write() return in elf_core_dump() One of the calls to dump_write() in elf_core_dump() was missing a check for failure (spotted by Coverity). Add the check to bring it into line with the other calls from this function.
