Subject: [PATCH] mac80211: make LED trigger names available early
|
|
|
|
The throughput trigger will require doing LED
|
|
classdev/trigger handling before register_hw(),
|
|
so drivers should have access to the trigger
|
|
names before it. If trigger registration fails,
|
|
this will still make the trigger name available,
|
|
but that's not a big problem since the default
|
|
trigger will the simply not be found.
|
