iwlagn: Re-enable RF_KILL interrupt when down

2011-02-07T21:02:14+00:00

With commit 554d1d027b19265c4aa3f718b3126d2b86e09a08 only one RF_KILL
interrupt will be seen by the driver when the interface is down.

Re-enable the interrupt when it occurs to see all transitions.

ath9k: Fix possible double free of PAPRD skb's

2011-02-04T21:11:39+00:00

This patch reverts the following commit
ath9k: remove bfs_paprd_timestamp from struct ath_buf_state

Under high interference/noisy environment conditions where PAPRD frames
fails heavily introduces a possibility of double freeing skb's and causes
kernel panic after some time.This patch reverts back to the original approach
of using paprd_timestamp before freeing the PAPRD frame skb's

wireless, wl1251: Fix potential NULL pointer dereference in wl1251_op_bss_info_changed()

2011-02-03T20:23:53+00:00

In drivers/net/wireless/wl1251/main.c:wl1251_op_bss_info_changed() we make
a call to ieee80211_beacon_get() which may return NULL, but we do not
check the return value before dereferencing the pointer.

iwlagn: overwrite EEPROM chain setting for 6250 devices

2011-02-02T21:38:58+00:00

6250 2x2 devices have 2 tx chain and 2 rx chain. For some reason,
the EEPROM contain incorrect information and indicate it only has single
tx chain. overwrite it with .cfg parameter to make sure both chain 'A' and
chain 'B' can be used for transmit and receive

will dump the already freed memory instead of the SPI buffer.

ath9k: Fix power save usage count imbalance on deinit

2011-01-28T20:27:20+00:00

While unloading the driver, the ps_usecount is incremented
before configuring gpio registers in deinit_device.
But it is failed to restore the ps_usecount after that.
The problem is that the chip is forcibly moved to FULL SLEEP
by radio_disable when mac80211 is reporting as idle
though ps_usecount is not zero.

This patch retores ps_usecount properly and ensures that
the chip is always moved to full sleep only if ps usage
count is zero which also helps in debugging deadbeef on
multivif case. And also fixes the following warning.

ath: DMA failed to stop in 10 ms AR_CR=0xdeadbeef AR_DIAG_SW=0xdeadbeef
ath: Could not stop RX, we could be confusing the DMA engine when we
start RX up
