2014-07-15mwifiex: fix corner case system hang issueAmitkumar Karwar
Sometimes pending internal scan commands are delayed to give preference to Tx traffic. 'scan_processing' flag has been checked at the beginning of delay timer routine to know if in the meantime scan operation has been cancelled. There is a corner case where pending scan commands are emptied after scan_processing flag check is passed. In this case wrong pointer returned by list_first_entry() is passed to list_del() which causes system hang. This patch fixes the issue by adding list_empty() check.

2014-07-15wlcore: user smaller sqn padding for GEMEliad Peller
On recovery, we increase the current seq num by WL1271_TX_SQN_POST_RECOVERY_PADDING in order to compensate for packets we might have missed during recovery.

2014-07-15ath10k: sanitize tx ring index access properlyMichal Kazior
The tx ring index was immediately trimmed with a bitmask. This discarded the 0xFFFFFFFF error case (which theoretically can happen when a device is abruptly disconnected) and led to using an invalid tx ring index. This could lead to memory corruption.

2014-07-15ath10k: fix bmi exchange tx/rx raceMichal Kazior
It was possible for tx completion not to be processed. In that case an old stack pointer was left on copy engine tx ring. Next bmi exchange would immediately pop it and use complete() on the completion struct there causing corruption. Make sure to wait for both tx and rx completions properly.

2014-07-14Bluetooth: cmtp: Remove unnecessary null testHimangi Saraogi
This patch removes the null test on ctrl. ctrl is initialized at the beginning of the function to &session->ctrl. Since session is dereferenced prior to the null test, session must be a valid pointer, and &session->ctrl cannot be null. The following Coccinelle script is used for detecting the change: @r@ expression e,f; identifier g,y; statement S1,S2; @@ *e = &f->g <+... f->y ...+> *if (e != NULL || ...)

2014-07-14ath10k: fix unregister deadlock when fw probe failsMichal Kazior
If firmware probing worker failed it called device_release_driver() which synchronously called remove() pci callback. The callback in turn waited for the worker that called it to finish resulting in a deadlock. Waiting for a completion instead of a worker, like some other drivers do, doesn't seem like the best idea either: Syscall Worker probe_fw() rmmod dev_lock() pci->remove() wait_for_completion() complete_all() device_release_driver() dev_lock() [sleep] free(ar) dev_unlock() [resume] There's no guarantee that Worker upon resuming can still access any data/code of the module. Leaving device bound to a driver is not as harmful as deadlocking so remove the call to device_release_driver() while a proper solution is figured out.

The functionality defined through these flags were actually firmware features which can change between firmware versions. To make it possible to support different firmware versions with the same driver, convert the flags to firmware feature flags. For backwards compatibility support for old ar6004 firmware FW API 3 or smaller images we forcefully set the feature bits in the driver. Starting from FW API 5 the firmware image needs to set them.
