commit 1adb2e2b5f85023d17eb4f95386a57029df27c88 upstream.

When the next beacon is sent, the ath_buf from the previous run is reused.
If getting a new beacon from mac80211 fails, bf-&gt;bf_mpdu is not reset, yet
the skb is freed, leading to a double-free on the next beacon tx attempt,
resulting in a system crash.

commit 0981c3b24ef664f5611008a6e6d0622fac6d892b upstream.

SKBs that are allocated in the HTC layer do not have callbacks
registered and hence ended up not being freed, Fix this by freeing
them properly in the TX completion routine.

commit b3cd8021379306c0be6932e4d3b4b01efc681769 upstream.

Trying to access the OTP memory on the AR9340
causes a data bus error like this:

commit 9c170e068636deb3e3f96114034bb711675f0faa upstream.

This reverts commit f74b9d365ddd33a375802b064f96a5d0e99af7c0.

Turns out reverting commit a240dc7b3c7463bd60cf0a9b2a90f52f78aae0fd
"ath9k_hw: Updated AR9003 tx gain table for 5GHz" was not enough to
bring the tx power back to normal levels on devices like the
Buffalo WZR-HP-G450H, this one needs to be reverted as well.

This revert improves tx power by ~10 db on that device

commit dd321acddc3be1371263b8c9e6c6f2af89f63d57 upstream.

When host_sleep_config command fails we should return error to
MMC core to indicate the failure for our device.

The misspelled variable is also removed as it's redundant.

commit a485e827f07bfdd0762059386e6e787bed6e81ee upstream.

This is an ISY IWL 2000. Probably a clone of Belkin F7D1102 050d:1102.
Its FCC ID is the same.

commit bf7e1abe434ba9e22e8dc04a4cba4ab504b788b8 upstream.

Some hardware has correct (!= 0xff) value of tssi_bounds[4] in the
EEPROM, but step is equal to 0xff. This results on ridiculous delta
calculations and completely broke TX power settings.

commit 8c6e30936a7893a85f6222084f0f26aceb81137a upstream.

bf-&gt;bf_next is only while buffers are chained as part of an A-MPDU
in the tx queue. When a tid queue is flushed (e.g. on tearing down
an aggregation session), frames can be enqueued again as normal
transmission, without bf_next being cleared. This can lead to the
old pointer being dereferenced again later.

This patch might fix crashes and "Failed to stop TX DMA!" messages.
