Subject: kern/mips/arc/init: Add missing grub_strdup() failure check
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f8c48cbedce59c02c359c9a35599d7568c8b98ce;p=thirdparty%2Fgrub.git

kern/mips/arc/init: Add missing grub_strdup() failure check

If grub_strdup() fails, it returns NULL and passing NULL further down to
the code can lead to segmentation fault or an undefined behavior.
