linux.git/net/nfc/core.c, branch v3.13 Linux kernel source tree NFC: Fix target mode p2p link establishment 2014-01-04T02:31:32+00:00 Arron Wang arron.wang@intel.com 2013-11-14T09:03:41+00:00 d31652a26bc9e752a99b6ac3b61353129934e451 With commit e29a9e2ae165620d, we set the active_target pointer from nfc_dep_link_is_up() in order to support the case where the target detection and the DEP link setting are done atomically by the driver. That can only happen in initiator mode, so we need to check for that otherwise we fail to bring a p2p link in target mode.

NFC: Set active target upon DEP up event reception 2013-09-24T23:35:41+00:00 Samuel Ortiz sameo@linux.intel.com 2013-08-21T12:46:20+00:00 e29a9e2ae165620d202f3ce45abd3a219b13ffb7 As we can potentially get DEP up events without having sent a netlink command, we need to set the active target properly from dep_link_is_up. Spontaneous DEP up events can come from devices that detected an active p2p target. In that case there is no need to call the netlink DEP up command as the link is already up and running.
