Subject: [PATCH 03/14] ideapad-laptop: Blacklist rfkill control on the Lenovo
|
|
Yoga 2 11
|
|
|
|
The Lenovo Yoga 2 11 always reports everything as blocked, causing userspace
|
|
to not even try to use the wlan / bluetooth even though they work fine.
|
|
|
|
Note this patch also removes the "else priv->rfk[i] = NULL;" bit of the
|
|
rfkill initialization, it is not necessary as the priv struct is allocated
|
|
with kzalloc.
