ath9k: Fix PS wrappers in ath9k_set_coverage_class

2011-08-24T17:52:28+00:00

this callback is called during suspend/resume and also via iw command.
it configures parameters like sifs, slottime, acktimeout in
ath9k_hw_init_global_settings where few REG_READ, REG_RMW are also done
and hence the need for PS wrappers

carl9170: Fix mismatch in carl9170_op_set_key mutex lock-unlock

2011-08-24T17:52:27+00:00

If is_main_vif(ar, vif) reports that we have to fall back
to software encryption, we goto err_softw; before locking ar->mutex.
As a result, we have unprotected call to carl9170_set_operating_mode
and unmatched mutex_unlock.

The patch fix the issue by adding mutex_lock before goto.

Found by Linux Driver Verification project (linuxtesting.org).

wl12xx: add max_sched_scan_ssids value to the hw description

2011-08-23T19:54:20+00:00

After commit 5a865ba, we require a separate value to indicate the
number of supported SSIDs in scheduled scans.  This patch adds a
proper value to the wl12xx driver.

This fixes a regression in 3.1-rc3 where scheduled scans were not
working properly with the wl12xx driver.

wl12xx: Fix validation of pm_runtime_get_sync return value

2011-08-23T19:54:20+00:00

wl1271_sdio_power_on checks if the return value of pm_runtime_get_sync
is non-zero, and if so bails out.
However, pm_runtime_get_sync can return a positive number which does not
suggest an error has occurred. This is problematic for two reasons:

1. The function will needlessly bail out without decrementing back the
   runtime PM reference counter.
2. wl1271_power_on only checks if wl1271_power_on return value is
   negative. This means that wl1271_power_on will continue even if
   wl1271_sdio_power_on bailed out. As a result, sdio transactions will
   be initiated without properly enabling the sdio function and claiming
   the host. This could even lead to a kernel panic.

Fix this by only checking that the return value of pm_runtime_get_sync
is non-negative.

wl12xx: Remove obsolete testmode NVS push command

2011-08-23T19:54:19+00:00

The testmode NVS push command is no longer in use. In addition, it has
several implementation issues that prevent it from working correctly:

1. wl1271_tm_cmd_configure relies on wl->chip.id being set. However,
   since the device was not necessarily booted by the time the function
   is called, wl->chip.id will be initialized to 0.
2. The NVS file is fetched by calling request_firmware() before it is
   possible to push an NVS file.
3. The maximum allowed size of nl binary payloads is not sufficient for
   pushing NVS files.
4. Pushing 128x NVS files will always fail due to a bug in the
   validation code.
5. In case the pushed NVS file is found invalid, the mutex will be kept
   locked and the nvs member will become a dangling pointer.

Since this feature is not being used, remove it completely instead of
fixing it.

ath9k_hw: Fix STA (AR9485) bringup issue due to incorrect MAC address

2011-08-22T18:21:41+00:00

Due to some recent optimization done in the way the mac address
bytes are written into the OTP memory, some AR9485 chipsets were
forced to use the first byte from the eeprom template and the
remaining bytes are read from OTP.

AR9485 happens to use generic eeprom template which has 0x1 as
the first byte causes issues in bringing up the card.

So fixed the eeprom template accordingly to address the issue.

rt2x00: do not drop usb dev reference counter on suspend

2011-08-22T18:21:40+00:00

When hibernating ->resume may not be called by usb core, but disconnect
and probe instead, so we do not increase the counter after decreasing
it in ->supend. As a result we free memory early, and get crash when
unplugging usb dongle.
