2010-11-17BKL: remove extraneous #include <smp_lock.h>Arnd Bergmann
The big kernel lock has been removed from all these files at some point, leaving only the #include. Remove this too as a cleanup. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2010-10-22[media] [RFC] radio-mr800: locking fixesHans Verkuil
- serialize the suspend and resume functions using the global lock. - do not call usb_autopm_put_interface after a disconnect. - fix a race when disconnecting the device.

2010-10-21[media] radio-mr800: fix locking orderHans Verkuil
Don't hold the lock before unregistering the device, since when the device is unregistered the datastruct containing the lock may be freed (if the refcount went to 0). Also fixed the framework documentation that erroneously suggested the wrong locking order as well.
