2012-01-27nfc: NULL vs zero in nci_activate_target()Dan Carpenter
This is a pointer so it should be NULL instead of zero.

2012-01-27mwifiex: pass priv pointer instead of adapterAvinash Patil
Pass mwifiex_private pointer directly to wmm_add_buf_txqueue() instead of passing adapter and then deriving priv again in mwifiex_get_priv_by_id(). This reduces a 'for' loop in TX path.

2012-01-24NFC: Add NCI multiple targets supportIlan Elias
Add the ability to select between multiple targets in NCI. If only one target is found, it will be auto-activated. If more than one target is found, then DISCOVER_NTF will be generated for each target, and the host should select one by calling DISCOVER_SELECT_CMD. Then, the target will be activated. If the activation fails, GENERIC_ERROR_NTF is generated. Signed-off-by: Ilan Elias <ilane@ti.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-01-24NFC: NFC core layer should not set the target_idxIlan Elias
The NFC core layer should not set the target_idx. Instead, the driver layer (e.g. NCI, PN533) should set the target_idx, so that it will be able to identify the target when its I/F (e.g. activate_target) is called. This is required in order to support multiple targets. Note that currently supported drivers (PN533 and NCI) don't use the target_idx in their implementation.

2012-01-24mac80211: in IBSS use the Auth frame to trigger STA reinsertionAntonio Quartulli
In case of a node re-joining the cell the sta_info structure belonging to it is first destroyed and then reinserted. In this way its internal state is reset. The joining operation is recognised thank the Auth frame being received. This operation is helpful in case of a node being rebooted that is joining the ad-hoc cell again, before its purge timeout on other nodes expires.
