2013-01-10NFC: Added error handling in event_received hci opsEric Lapuyade
There is no use to return an error if the caller doesn't get it. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-01-10NFC: Fixed nfc core and hci unregistration and cleanupEric Lapuyade
When an adapter is removed, it will unregister itself from hci and/or nfc core. In order to do that safely, work tasks must first be canceled and prevented to be scheduled again, before the hci or nfc device can be destroyed.

2013-01-10NFC: nfcwilink: Use devm_kzallocJulia Lawall
devm_kzalloc allocates memory that is released when a driver detaches. This patch uses devm_kzalloc for data that is allocated in the probe function of a platform device and is only freed in the remove function.

2013-01-10NFC: pn533: Introduce ops for frame logicWaldemar Rymarkiewicz
Encapsulate whole frame logic (tx/rx frame structure and size) inside the ops structure to make the core driver generic for devices which handle frames in non standard menner (different then pn533 spec say).

2013-01-10NFC: pn533: Cleanup pn533_cmd_complete_tWaldemar Rymarkiewicz
'params' arg in pn533_cmd_complete_t definition has been deprecated and currently is not in use (resp skb is pass in arg ptr), so remove it. Also 'params_len' arg is used as a transfer status indicator, so simply reword it appropriately.

2013-01-10NFC: pn533: Remove deprecated dev->out_frame buffWaldemar Rymarkiewicz
As it's not used anymore get rid of that buffer. Signed-off-by: Waldemar Rymarkiewicz <waldemar.rymarkiewicz@tieto.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-01-10NFC: pn533: Use skb in __pn533_send_cmd_frame_asynWaldemar Rymarkiewicz
__pn533_send_cmd_frame_async() should be frame type independent. So, don't use pn533_frame type params and instead use skb for req and resp pointers. Signed-off-by: Waldemar Rymarkiewicz <waldemar.rymarkiewicz@tieto.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-01-10NFC: pn533: Don't use out_frame in pn533_send_ackWaldemar Rymarkiewicz
dev->out_frame buffer is much bigger for ACK frame needs. Use local buffer instead. Signed-off-by: Waldemar Rymarkiewicz <waldemar.rymarkiewicz@tieto.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-01-10NFC: pn533: Cleanup debug messagesWaldemar Rymarkiewicz
Remove debug messages which do not include valueable informations in debug mode. Add some new ones for better tracking or reword when if necessary. Signed-off-by: Waldemar Rymarkiewicz <waldemar.rymarkiewicz@tieto.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-01-10NFC: pn533: Fix urb->status handlingWaldemar Rymarkiewicz

2013-01-10NFC: pn533: Remove unused pn533_send_cmd_frame_asyWaldemar Rymarkiewicz
Remove obsolete send async api as it's no longer used. Remove global dev->in_frame as well, as each packet is kept is a seperate skb struct now, so that's not used anymore. Signed-off-by: Waldemar Rymarkiewicz <waldemar.rymarkiewicz@tieto.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2013-01-10NFC: pn533: Del frame logic from Data Exchange cmdWaldemar Rymarkiewicz
Remove frame logic from transceive cb using new iface for async send. For pn533_wq_mi_recv() use pn533_send_cmd_direct_async which sends the cmd directly to the hardware, skipping cmd queue.

2013-01-10NFC: llcp: Fix Rx memory leakSamuel Ortiz
The reference count bump on the llcp Rx path is leading to a memory leak whenever we're not receiving an I frame. We fix that by removing the refcount bump (drivers must not free their received skb) and using it only in the I frame path, when the frame is actually queued. In that case, the skb will only be freed when someone fetches it from userspace. in all other cases, LLCP received frames will be freed when leaving the Rx work queue.

2013-01-10NFC: llcp: Remove the tx backlog queueSamuel Ortiz
Not only it was improperly use to queue backlogged RX skbuffs, but it was also not processed at all. If the socket receive queue is full we simply drop the incoming packets. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-01-10NFC: pn533: Remove pn533_send_cmd_frame_syncWaldemar Rymarkiewicz
Remove obsolate pn533_send_cmd_frame_sync() and use previously added new iface for sync send. The new interface require the use of individual skb for each cmd which removes some memcpy calls and hides frame logic.

2013-01-10NFC: pn533: Add pn533_alloc_skb for req allocationWaldemar Rymarkiewicz

2013-01-10NFC: pn533: Add a new pn533_send_sync ifaceWaldemar Rymarkiewicz
It is intended to replace pn533_send_cmd_frame_sync() iface which requires from the caller to create complete frame. The new function constructs a complete frame itself and sends it out in sync manner. This way frame logic is hidden from the caller. pn533_send_cmd_sync() returns ERR_PTR in case of an error or a pointer to valid response sk_buff otherwise. The pointer must be freed by the caller when it's been consumed. Signed-off-by: Waldemar Rymarkiewicz <waldemar.rymarkiewicz@tieto.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-01-10NFC: pn533: Add a new pn533_send_data_async ifaceWaldemar Rymarkiewicz
This iface is intended to be used with DEP transfers. It differs from pn533_send_cmd_async() in the way the response skb is allocated. Signed-off-by: Waldemar Rymarkiewicz <waldemar.rymarkiewicz@tieto.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-01-10NFC: pn533: Add a new pn533_send_cmd_async ifaceWaldemar Rymarkiewicz
This is intendend to replace pn533_send_cmd_frame_async() which requires from the caller to create a complete frame. The new function constructs a frame and sends it out which hides the frame logic and avoid code duplication. The caller has to allocate skb and put its payload there, and finally provide the skb together with a complete cb to pn533_send_cmd_async(). Response skb is allocated by the core part and pass to the caller cb. Next, the caller has to free it when is not needed anymore or pass it up to the stack.

2013-01-10NFC: pn533: Remove pointless flags paramWaldemar Rymarkiewicz
__pn533_send_cmd_frame_async() is called when lock is held so GFP_KERNEL flag will be always used. Thus, having extra param does not optimise the code. Signed-off-by: Waldemar Rymarkiewicz <waldemar.rymarkiewicz@tieto.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-01-10NFC: pn533: Add frame header length defineWaldemar Rymarkiewicz
PN533_CMD_DATAEXCH_HEAD_LEN includes a frame header length which is not seen at a glance. It can be missleading, so split it and define the frame header length explicitly. Signed-off-by: Waldemar Rymarkiewicz <waldemar.rymarkiewicz@tieto.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2013-01-07mwifiex: access interrupt status only while holding lockAvinash Patil

2013-01-07bcma: mips: explicit assign IRQ numbersHauke Mehrtens
The assignment of the IRQs to the cores of the chips by iterating over the cores is complicated and causes problems with SoC like the BCM4706 with two GMAC core where just one should get a dedicated IRQ number. Now the code assigns the same IRQs to the cores as the code from the Broadcom SDK does. If the SoC is not know the current assigned IRQs are only read out and an error message is printed.

2013-01-07mwl8k: Handle watchdog event with highest prioriryYogesh Ashok Powar
Currently, command path waits till all the tx host queues are empty. Whenever watchdog event is raised, firmware expects driver to destroy ampdu queues immediately. This requires corresponding commands i.e. mwl8k_cmd_get_watchdog_bitmap and mwl8k_destroy_ba to be sent without waiting for the tx queues to be completely empty. Use "watchdog_event_pending" to ensure the above mentioned two commands are sent down immediately.

2013-01-07mwl8k: Handle Watchdog events for the new ampdu streamsYogesh Ashok Powar
With more ampdu streams, we need to handle watchdog events for the new ampdu streams. Handle these events appropriately. Earlier mwl8k_cmd_get_watchdog_bitmap used to return only one stream index and hence bitwise operations on the return value were not required. Now the function returns a bitmap with different bits are mapped with different stream indices.

2013-01-07mwl8k: changing mwl8k_destroy_ba prototypeYogesh Ashok Powar
Currently, mwl8k_ampdu_stream is passed as one of the argument to the function mwl8k_destroy_ba. Instead of this pass only the stream index. This will be helpful during watchdog event handling when bitmap of stream indices are received.
