| Subject: eeepc-laptop: add hotplug_disable parameter |
| |
| commit 322a1356be96bcc4b97e8e370f6468c821330077 upstream. |
| |
| Some new models need to disable wireless hotplug. |
| For the moment, we don't know excactly what models need that, |
| except 1005HA. |
| Users will be able to use that param as a workaround. |
