2012-05-14Bluetooth: notify userspace of security level changeGustavo Padovan
It fixes L2CAP socket based security level elevation during a connection. The HID profile needs this (for keyboards) and it is the only way to achieve the security level elevation when using the management interface to talk to the kernel (hence the management enabling patch being the one that exposes this issue). It enables the userspace a security level change when the socket is already connected and create a way to notify the socket the result of the request. At the moment of the request the socket is made non writable, if the request fails the connections closes, otherwise the socket is made writable again, POLL_OUT is emmited.

2012-05-14rtlwifi: fix for race condition when firmware is cachedLarry Finger
In commit b0302ab, the rtlwifi family of drivers was converted to use asynchronous firmware loading. Unfortumately, the implementation was racy, and the ieee80211 routines could be started before rtl_init_core() was called to setup the data. This patch fixes the bug noted in https://bugzilla.kernel.org/show_bug.cgi?id=43187.

2012-05-14[media] radio-si470x-usb: remove autosuspend, implement suspend/resumeHans Verkuil
The radio-si470x-usb driver supported both autosuspend and it stopped the radio the moment the last user of the radio device closed it. However, that was very confusing since if you play the audio from the device (e.g. through arecord -D ... | aplay) then no sound would play unless you had the radio device open at the same time, even though there is no need to do anything with that node. On the other hand, the actual suspend/resume functions didn't do anything, which would fail if you *did* have the radio node open at that time. So: - remove autosuspend (bad idea in general for USB radio devices) - move the start/stop out of the open/release functions into the resume/suspend functions.
