2012-08-21Bluetooth: Fix establishing ESCO linksVinicius Costa Gomes
Commit 4cd2d98340b4f03d5532c30fdaeb451b035429cb "Bluetooth: Simplify the connection type handling" broke the creation of ESCO links. This patch adds a type parameter to hci_connect_sco() so it creates the connection of the right kind.

2012-08-21Bluetooth: mgmt: Add device disconnect reasonMikel Astiz
MGMT_EV_DEVICE_DISCONNECTED will now expose the disconnection reason to userland, distinguishing four possible values: 0x00 Reason not known or unspecified 0x01 Connection timeout 0x02 Connection terminated by local host 0x03 Connection terminated by remote host Note that the local/remote distinction just determines which side terminated the low-level connection, regardless of the disconnection of the higher-level profiles. This can sometimes be misleading and thus must be used with care. For example, some hardware combinations would report a locally initiated disconnection even if the user turned Bluetooth off in the remote side.

2012-08-15Bluetooth: Add type information to the hci_connect() debug statementVinicius Costa Gomes

2012-08-15Bluetooth: Refactor SCO connection into its own functionVinicius Costa Gomes
We can do the same that we did for the other link types, for SCO connections. The only thing that's worth noting is that as SCO links need an ACL link, this functions uses the function that adds an ACL link.

2012-08-13mac80211: fix unnecessary beacon update after peering status changeMarco Porsch
ieee80211_bss_info_change_notify is called everytime a peer link is established or closed, because the accepting_plinks flag in the meshconf IE *might* have changed. With this patch the corresponding functions return the BSS_CHANGED_BEACON flag when a beacon update is necessary. Also it makes mesh_accept_plinks_update the common place to update the accepting_plinks flag. mesh_accept_plinks_update is called upon plink change and also periodically from ieee80211_mesh_housekeeping. Thus, it also picks up changes of local->num_sta. Signed-off-by: Marco Porsch <marco.porsch@etit.tu-chemnitz.de> Acked-by: Thomas Pedersen <thomas@cozybit.com> Signed-off-by: John W.

2012-08-10brcmsmac: document firmware dependenciesJeff Mahoney
The brcmsmac driver requests firmware but doesn't document the dependency. This means that software that analyzes the modules to determine if firmware is needed won't detect it. Specifically, (at least) openSUSE won't install the kernel-firmware package if no hardware requires it. This patch adds the MODULE_FIRMWARE directives.
