wifi: rt2x00: Fix memory leak when handling surveys

2023-04-03T13:44:27+00:00

When removing a rt2x00 device, its associated channel surveys
are not freed, causing a memory leak observable with kmemleak:

Fix this by freeing the channel surveys on device removal.

Tested with a RT3070 based USB wireless adapter.

wifi: rt2x00: Remove useless else if

2023-01-16T16:23:49+00:00

The assignment of the else and else if branches is the same, so the else
if here is redundant, so we remove it.

wifi: rt2x00: use explicitly signed or unsigned types

2022-10-21T06:59:39+00:00

On some platforms, `char` is unsigned, but this driver, for the most
part, assumed it was signed. In other places, it uses `char` to mean an
unsigned number, but only in cases when the values are small. And in
still other places, `char` is used as a boolean. Put an end to this
confusion by declaring explicit types, depending on the context.

wifi: mac80211: add wake_tx_queue callback to drivers

2022-10-10T09:00:03+00:00

mac80211 is fully switching over to the internal TX queue (iTXQ)
implementation. Update all drivers not yet providing the now mandatory
wake_tx_queue() callback.

As an side effect the netdev interfaces of all updated drivers will
switch to the noqueue qdisc.
