Subject: multiboot: Use signed type for negative error numbers
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5f370b14639370b1e010fac5b1fd094e502a781e;p=qemu.git

multiboot: Use signed type for negative error numbers

In mb_mod_length a return value is stored that is negative in error case. With
an unsigned type the check goes wrong.
