Subject: [PATCH] rules: update qemu hid rules
|
|
|
|
Update comment to be a bit more specific.
|
|
|
|
Change match to blacklist the serial number of the broken devices
|
|
instead of whitelisting the serial number of the fixed devices.
|
|
This allows to do something useful with the serial number in the
|
|
future.
