No callers of get_opt_value() pass in a NULL for the "value" parameter,
|
|
so the check is redundant.
|
|
|
|
RHEL8 notes:
|
|
|
|
- Context difference in "util/qemu-option.c", function get_opt_value();
|
|
upstream has commit 5c99fa375da1 ("cutils: Provide strchrnul",
|
|
2018-06-29), part of v3.0.0, but downstream lacks it. Harmless, because
|
|
said upstream commit only refactors get_opt_value().
