Subject: [PATCH 1/2] Revert "dell-laptop: Remove rfkill code"
|
|
|
45b5fd0 |
|
|
|
45b5fd0 |
Without rfkill functionality in dell-laptop I have the following problems:
|
|
|
45b5fd0 |
-If the hardware radio switch is set to disable the radio, then userspace
|
|
|
45b5fd0 |
will still think it can use wireless and bluetooth.
|
|
|
45b5fd0 |
-The wwan / 3g modem cannot be soft blocked without the dell-laptop rfkill
|
|
|
45b5fd0 |
functionality
|
|
|
45b5fd0 |
|
|
|
45b5fd0 |
I know the rfkill functionality was removed from the dell-laptop driver because
|
|
|
45b5fd0 |
it caused more problems then it fixed, and the blacklist for it was growing out
|
|
|
45b5fd0 |
of control.
|
|
|
45b5fd0 |
|
|
|
45b5fd0 |
But in the thread discussing this Dell mentioned that they only QA the rfkill
|
|
|
45b5fd0 |
acpi interface on Latitudes and indeed there have been no blacklist entries
|
|
|
45b5fd0 |
for Latitudes. Therefor I would like to bring the rfkill functionality back
|
|
|
45b5fd0 |
only for Latitudes. This patch is a straight-forward revert. The next patch
|
|
|
45b5fd0 |
in this set will drop the blacklist and replace it with a Latitude check.
|
|
|
45b5fd0 |
|
|
|
45b5fd0 |
This reverts commit a6c2390cd6d2083d27a2359658e08f2d3df375ac.
