2015-02-06brcm80211: Delete unnecessary checks before two function callsMarkus Elfring
The functions brcmu_pkt_buf_free_skb() and usb_free_urb() test whether their argument is NULL and then return immediately. Thus the test around the call is not needed. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-01-29brcmfmac: SDIO: avoid using bus state for private states.Hante Meuleman
Each bus driver is maintaing an exported bus state indicating if upper layers can or cannot send data. SDIO is using this state also for more private states. This makes handling the states and state changes complex. This patch minimises the exposed states and makes SDIO keep track of an internal state where necessary.

2015-01-29brcmfmac: wait for driver to go idle during suspendArend van Spriel
Before going in suspend state the watchdog thread needs to put the device in bus sleep state, which assures it can go in deep-sleep state during D3 state.

Control frames are normally handled outside DPC, but sometimes within DPC. To simplify code always handle control within DPC.

2015-01-29brcmfmac: prevent possible deadlock on resuming SDIO device.Hante Meuleman
When the system is resumed a deadlock can occur when DPC gets entered before resume is complete. This patch fixes this by properly checking the suspend state outside the claim_host code block.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next John W. Linville says: ==================== pull request: wireless-next 2014-11-07 Please pull this batch of updates intended for the 3.19 stream! For the mac80211 bits, Johannes says: "This relatively large batch of changes is comprised of the following: * large mac80211-hwsim changes from Ben, Jukka and a bit myself * OCB/WAVE/11p support from Rostislav on behalf of the Czech Technical University in Prague and Volkswagen Group Research * minstrel VHT work from Karl * more CSA work from Luca * WMM admission control support in mac80211 (myself) * various smaller fixes, spelling corrections, and minor API additions" For the Bluetooth bits, Johan says: "Here's the first bluetooth-next pull request for 3.19. The vast majority of patches are for ieee802154 from Alexander Aring with various fixes and cleanups. There are also several LE/SMP fixes as well as improved support for handling LE devices that have lost their pairing information (the patches from Alfonso). Jukka provides a couple of stability fixes for 6lowpan and Szymon conformance fixes for RFCOMM. For the HCI drivers we have one new USB ID for an Acer controller as well as a reset handling fix for H5." For the Atheros bits, Kalle says: "Major changes are: o ethtool support (Ben) o print dev string prefix with debug hex buffers dump (Michal) o debugfs file to read calibration data from the firmware verification purposes (me) o fix fw_stats debugfs file, now results are more reliable (Michal) o firmware crash counters via debugfs (Ben&me) o various tracing points to debug firmware (Rajkumar) o make it possible to provide firmware calibration data via a file (me) And we have quite a lot of smaller fixes and clean up." For the iwlwifi bits, Emmanuel says: "The big new thing here is netdetect which allows the firmware to wake up the platform when a specific network is detected. Along with that I have fixes for d3 operation. The usual amount of rate scaling stuff - we now support STBC. The other commit that stands out is Johannes's work on devcoredump. He basically starts to use the standard infrastructure he built." Along with that are the usual sort of updates and such for ath9k, brcmfmac, wil6210, and a handful of other bits here and there... Please let me know if there are problems! ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
