Subject: [PATCH] qemu: Improve qemuDomainChrTargetDefValidate()
|
|
|
404507 |
|
|
|
404507 |
Instead of validating each target type / address type combination
|
|
|
404507 |
separately, create a small helper to perform the matching and
|
|
|
404507 |
collapse all existing checks into a single one.
