* net: Fix files explicitly needing to include module.hPaul Gortmaker2011-10-311-0/+1
| | | | | | | | | With calls to modular infrastructure, these files really needs the full module.h header. Call it out so some of the cleanups of implicit and unrequired includes elsewhere can be cleaned up. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
* NFC: use after free on errorDan Carpenter2011-09-271-8/+6
| | | | | | | | | | | We returned a freed variable on some error paths when the intent was to return a NULL. Part of the reason this was missed was that the code was confusing because it had too many gotos so I removed them and simplified the flow a bit.

* NFC: protect nci_data_exchange transactionsIlan Elias2011-09-273-2/+12
| | | | | | | | | | Protect 'cb' and 'cb_context' arguments in nci_data_exchange. In fact, this implements a queue with max length of 1 data exchange transactions in parallel.

* NFC: implicitly deactivate in nci_start_pollIlan Elias2011-09-271-1/+6
| | | | | | | | | | | When start_poll is called, and a target was implicitly activated, we need to implicitly deactivate it. On the other hand, when the target was activated by the user, we should not deactivate it.

* NFC: basic NCI protocol implementationIlan Elias2011-09-209-0/+1633
| | | | | | | | | The NFC Controller Interface (NCI) is a standard communication protocol between an NFC Controller (NFCC) and a Device Host (DH), defined by the NFC Forum. Signed-off-by: Ilan Elias <ilane@ti.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* NFC: move nfc.h from include/net to include/net/nfcIlan Elias2011-09-201-1/+1
| | | | | | | | The file nfc.h was moved from include/net to include/net/nfc, since new NFC header files will be added to include/net/nfc. Signed-off-by: Ilan Elias <ilane@ti.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* NFC: Add dev_up and dev_down control operationsIlan Elias2011-09-203-0/+137
| | | | | | | | | Add 2 new nfc control operations: dev_up to turn on the nfc device dev_down to turn off the nfc device Signed-off-by: Ilan Elias <ilane@ti.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* NFC: Reserve tx head and tail roomSamuel Ortiz2011-08-242-8/+11
| | | | | | | | | We can have the NFC core layer allocating the tx head and tail room for the drivers and avoid 1 or more SKBs copy on write on the Tx path. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
