[Qemu-devel] [PATCH 6/8] linux-user: Check dump_write() return in elf_co


From: Peter Maydell
Subject: [Qemu-devel] [PATCH 6/8] linux-user: Check dump_write() return in elf_core_dump()
Date: Tue, 12 Jul 2016 13:02:17 +0100

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.
