From: Stefan Weil <[email protected]> Error report from cppcheck: block/vdi.c:122: error: Using sizeof for array given as function argument returns the size of pointer. block/vdi.c:128: error: Using sizeof for array given as function argument returns the size of pointer.
Fix both by setting the correct size. The buggy code is only used when QEMU is build without uuid support. The bug is not critical, so there is no urgent need to apply it to old versions of QEMU.
