2012-10-31dmaengine: sirf: fix a typo in moving running dma_desc to active queueBarry Song
commit 26fd12209c08fe947be1828896ef4ffc5bd0e6df upstream. list_move_tail(&schan->queued, &schan->active) makes the list_empty(schan->queued) undefined, we either should change it to: list_move_tail(schan->queued.next, &schan->active) or list_move_tail(&sdesc->node, &schan->active) Signed-off-by: Barry Song <Baohua.Song@csr.com> Signed-off-by: Vinod Koul <vinod.koul@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2012-10-31qmi_wwan/cdc_ether: move Novatel 551 and E362 to qmi_wwanDan Williams
commit f8295ec22cb0f1ee6849b862addbfa3ea9320755 upstream. These devices provide QMI and ethernet functionality via a standard CDC ethernet descriptor. But when driven by cdc_ether, the QMI functionality is unavailable because only cdc_ether can claim the USB interface. Thus blacklist the devices in cdc_ether and add their IDs to qmi_wwan, which enables both QMI and ethernet simultaneously.

2012-10-31Bluetooth: SMP: Fix setting unknown auth_req bitsJohan Hedberg
commit 065a13e2cc665f6547dc7e8a9d6b6565badf940a upstream. When sending a pairing request or response we should not just blindly copy the value that the remote device sent. Instead we should at least make sure to mask out any unknown bits. This is particularly critical from the upcoming LE Secure Connections feature perspective as incorrectly indicating support for it (by copying the remote value) would cause a failure to pair with devices that support it.

2012-10-31b43: Fix oops on unload when firmware not foundLarry Finger
commit f89ff6441df06abc2d95f3ef67525923032d6283 upstream. When b43 fails to find firmware when loaded, a subsequent unload will oops due to calling ieee80211_unregister_hw() when the corresponding register call was never made.

2012-10-31mac80211: check if key has TKIP type before updating IVStanislaw Gruszka
commit 4045f72bcf3c293c7c5932ef001742d8bb5ded76 upstream. This patch fix corruption which can manifest itself by following crash when switching on rfkill switch with rt2x00 driver: https://bugzilla.redhat.com/attachment.cgi?id=615362 Pointer key->u.ccmp.tfm of group key get corrupted in: ieee80211_rx_h_michael_mic_verify(): /* update IV in key information to be able to detect replays */ rx->key->u.tkip.rx[rx->security_idx].iv32 = rx->tkip_iv32; rx->key->u.tkip.rx[rx->security_idx].iv16 = rx->tkip_iv16; because rt2x00 always set RX_FLAG_MMIC_STRIPPED, even if key is not TKIP. We already check type of the key in different path in ieee80211_rx_h_michael_mic_verify() function, so adding additional check here is reasonable.

2012-10-31mac80211: connect with HT20 if HT40 is not permittedJohannes Berg
commit 3a40414f826a8f1096d9b94c4a53ef91b25ba28d upstream. Some changes to fix issues with HT40 APs in Korea and follow-up changes to allow using HT40 even if the local regulatory database disallows it caused issues with iwlwifi (and could cause issues with other devices); iwlwifi firmware would assert if you tried to connect to an AP that has an invalid configuration (e.g. using HT40- on channel 140.) Fix this, while avoiding the "Korean AP" issue by disabling HT40 and advertising HT20 to the AP when connecting.

2012-10-31ARM: SAMSUNG: Add naming of s3c64xx-spi devicesHeiko Stuebner
commit 308b3afb97dc342e9c4f958d8b4c459ae0e22bd7 upstream. Commit a5238e360b71 (spi: s3c64xx: move controller information into driver data) introduced separate device names for the different subtypes of the spi controller but forgot to set these in the relevant machines. To fix this introduce a s3c64xx_spi_setname function and populate all Samsung arches with the correct names. The function resides in a new header, as the s3c64xx-spi.h contains driver platform data and should therefore at some later point move out of the Samsung include dir. Tested on a s3c2416-based machine.

2012-10-31USB: mct_u232: fix broken closeJohan Hovold
commit 5260e458f5eff269a43e4f1e9c47186c57b88ddb upstream. Make sure generic close is called at close. The driver relies on the generic write implementation but did not call generic close. Note that the call to kill the read urb is not redundant, as mct_u232 uses an interrupt urb from the second port as the read urb and that generic close therefore fails to kill it. Compile-only tested. Signed-off-by: Johan Hovold <jhovold@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

commit a8f2ae7a3aa59079d7e7e1ddf5007f03532f458c upstream. Fix port-data memory leak by moving port data allocation and deallocation to port_probe and port_remove. Since commit 0998d0631001288 (device-core: Ensure drvdata = NULL when no driver is bound) the port private data is no longer freed at release as it is no longer accessible. Note that the write waitqueue was initialised but never used. Compile-only tested. Signed-off-by: Johan Hovold <jhovold@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2012-10-31USB: usb-wwan: fix multiple memory leaks in error pathsJohan Hovold
commit b8f0e82044c9ba40e92340c8a6d47d6bd6d819bc upstream. Fix port-data memory leak in usb-serial probe error path by moving port data allocation to port_probe. Since commit a1028f0abf ("usb: usb_wwan: replace release and disconnect with a port_remove hook") port data is deallocated in port_remove. This leaves a possibility for memory leaks if usb-serial probe fails after attach but before the port in question has been successfully registered. Note that this patch also fixes two additional memory leaks in the error path of attach should port initialisation fail for any port as the urbs were never freed and neither was the data of any of the successfully initialised ports.
