Subject: [PATCH] Check and report for incomplete 'global' option format
mainline inclusion commit 818e1636080768749dc826acd4825e71828ec7e6 category:
bugfix
---------------------------------------------------------------
Qemu might crash when provided incomplete '-global' option.
For example:
qemu-system-x86_64 -global driver=isa-fdc
qemu-system-x86_64: ../../devel/qemu/qapi/string-input-visitor.c:394:
string_input_visitor_new: Assertion `str' failed.
Aborted (core dumped)
Fixes: 3751d7c43f795b ("vl: allow full-blown QemuOpts syntax for -global")
