rtlwifi: rtl8188ee: initialize packet_beacon

2014-05-15T07:56:09+00:00

commit 328e203fc35f0b4f6df1c4943f74cf553bcc04f8 upstream.

static code analysis from cppcheck reports:

[drivers/net/wireless/rtlwifi/rtl8188ee/trx.c:322]:
  (error) Uninitialized variable: packet_beacon

packet_beacon is not initialized and hence packet_beacon
contains garbage from the stack, so set it to false.

ath9k: fix ready time of the multicast buffer queue

2014-05-15T07:56:06+00:00

commit 3b3e0efb5c72c4fc940af50b33626b8a78a907dc upstream.

qi->tqi_readyTime is written directly to registers that expect
microseconds as unit instead of TU.
When setting the CABQ ready time, cur_conf->beacon_interval is in TU, so
convert it to microseconds before passing it to ath9k_hw.

This should hopefully fix some Tx DMA issues with buffered multicast
frames in AP mode.

iwlwifi: dvm: take mutex when sending SYNC BT config command

commit 82e5a649453a3cf23516277abb84273768a1592b upstream.

There is a flow in which we send the host command in SYNC
mode, but we don't take priv->mutex.

b43: Fix machine check error due to improper access of B43_MMIO_PSM_PHY_HDR

2014-05-15T07:55:59+00:00

commit 12cd43c6ed6da7bf7c5afbd74da6959cda6d056b upstream.

Register B43_MMIO_PSM_PHY_HDR is 16 bit one, so accessing it with 32b
functions isn't safe. On my machine it causes delayed (!) CPU exception:
